Methods for supporting the flow of information about the environmental factors in emergency services and prevent action

Abstract: With the development of systems forming the human environment, such as production systems, energy, transport, information be increased the impact the crisis situations on their operation. The basis for the smooth operation of prevention and rescue services in countering the effects of crisis events (such as mass events) is the close coordination and cooperation. Successful operation of emergency services and prevention requires efficient decision-making at all levels of rescue action. Currently, the development of methods and tools of Augmented Reality allows for the delivery of information to support decisions on a wide range of activities undertaken by man. Effective use of this technology requires the collection of information characterizing the environment of potential crises and to provide of this information to the emergency services and prevention. In the context of the current disposal of the central organization of emergency and prevention services in the publication we show supporting for information flows. On this basis, one can consider that the tools of Augmented Reality may significantly contribute to the success of the operation of the emergency services and prevention.

Civilizations and production methods

Abstract: The article presents issues related to the impact of a given civilization on the quality of production techniques and methods used by a given society/in a given country. It is based on the comparative science of civilizations founded by Feliks Koneczny. An essence of a civilization is explained and a mutual interaction between civilizations (the battle of civilizations) is pointed out. Five civilization's components (the categories of social being) are described as a tool for identifying the type of a given civilization. That components' interaction (having influence on a given civilization's resilience and ability to meet the social needs) is highlighted. Seven civilization types existing nowadays (according to F. Koneczny) are characterized and their capabilities to develop science, economy and to generate capital goods are discussed. A conclusion is that the Latin civilization is the most capable. Using presented distinguishing marks civilizations are divided (acc. F. Koneczny) into two groups: collectivistic and individualistic. A model of a new civilization introduced by Richard Nikolaus Coudenhove-Kalergi is presented and is confronted with the Latin civilization. It is stated that the mentioned model of European civilization meets the criteria of the collectivistic civilization. Properties of an economic development and production in societies of collectivistic and individualistic civilizations are identified as consequences of the choice of a social system.

How to merge environmental information using meta-analysis

Abstract: The article describes how to merge (integrate) information derived from different environmental studies. For such methods that are designed especially for combining of multi-sources information the term meta-analysis was coined in the statistical literature. Meta-analysis is a large family of advanced and continuously developed methods that go far beyond the well-known classical methods of data merger (integration), i.e. based on correlation or regression analysis. This issue is especially important in practice of environmental research when many results of detailed, but independent studies are available, e.g. obtained by different scientific groups, at different time or during different campaigns, from samples of different sizes etc., whose results must be properly generalized in order to take well-founded and precise conclusions.

Disaggregation of SO2 and PM2.5 emissions from small domestic combustion sources located in southwestern polish provinces: case study

Abstract: The aim of this study is to present disaggregation for SO2 and PM2.5 emissions from small domestic sources. As suggested by Dong and Liang [5], the problem is to analyse air emission from scattered sources (households). Data submitted for Poland [14] indicate that small domestic boilers are one of main sources of air pollutant emission. Their shares in 2013 national total were about 34% for SO2 and 51% for PM2.5 respectively. Results from [21] underline the significance of that source. Moreover, the current analysis found connection between small domestic combustion and air quality worsening in local scale. Despite the fact, solid fuels will remain the main energy resource in the near future [22]. To carry out presented analysis, we used emission data submitted for international purposes [14] and selected statistics published by the Central Statistical Office of Poland [15, 16]. Selected data were derived also from study carried out by Hławiczka et al. [9] for Polish-Czech Republic border region.

Selected satellite remote sensing methods in environmental monitoring of mining areas

Abstract: Environmental protection and monitoring in mining areas is a complex issue which includes a variety of aspects, as a consequence of complicated activities related to the mining of mineral resources. A degradation of environment is different depending on areas where hard coal is mined and where lignite is mined in open cast mines. Among others, related main environmental problems are: subsidence, fire hazard on heaps of coal wastes, soil moisture changes, land use changes and complex environmental degradation caused by one or more of the above-mentioned factors. Investigating and monitoring of those aspects of environment in the mining areas, especially over the vast areas, using field methods, is difficult, time consuming and expensive. Systematic using of remote sensing methods, especially based on satellite data, as supplementary or even as primary methods instead of field measurements can save a lot of money. An undoubted advantage of remote sensing is acquiring of information at virtually the same time, which ensures consistency of time of the measurements. It is very important in monitoring of phenomena with high time variability (such as soil moisture). Another advantage is possibility to analyze initial state of environment using historical data for many years ago. Remote sensing methods are also convenient tools for planning, supervising and monitoring the rehabilitation of degraded areas.

Registering coal cutting force using the POU-BW/01-WAP device

Abstract: This article presents the structure and operating principle of a globally unique device which allows for the measurement of forces involved in the process of cutting (coal breaking), named POU-BW/01-WAP by the author. It is the only device in the world which makes it possible to directly determine the value of the two component forces involved in the coal cutting process: the cutting force Fs and the contact force between the pick and the coal solid Fd. Determining the value of the forces involved in the cutting process is possible with the use of two independent measurement blocks, each consisting of strain gauges. The forces were measured using a tangential-rotary pick utilised in drum shearers. The calibration process of force strain gauges has been described and the results of verification research presented. The device has been approved with the ATEX certificate, which allows it to be operated in real environment as a device intended for use in explosive atmospheres in accordance with the 94/9/EC directive.

Reducing dust concentration in mines

Abstract: An important and most frequently used means of dust disposal in mines is water spray. Recently, it was found that its efficient operation depends on the relation between the size of the dust grains and water drops. The article gives examples showing that at the current level of water jet design, this requirement is not met. This leads to the conclusion that it is necessary to develop a new type of nozzles.

Lining of drums in belt conveyors and his influence on the transfer of tractive force

Abstract: At every point of contact between the belt and the drum, the equalization of velocities occurs, which manifests itself in creeping even in the case of relatively dry and clean contact surfaces. This leads to the development of heat absorbed by both the elements – the belt and the drum lining. In contrast to the belt, the temperature in the drum lining grows until a certain steady limit that depends on many factors is reached. If the temperature of surface of drum lining of about 60 0C is exceeded, structural changes in the material of this drum lining already occur, and at the next increase in the temperature, a danger of belt ignition and of the destruction of drive unit threatens. This can be avoided by lining the drum with new materials that eliminate friction on the contact surfaces and that are heat resistant.

Analysis of changing mine fire development

Abstract: Mining coal seams in Polish coal mines are connected with natural hazards occurrence. One of this hazards is fire hazard resulting from mining combustible material. Each type of coal is more or less combustible. Although in recent years the number of fires has decreased significantly, the occurrence of fire in the underground mine is very dangerous. It endangers miners’ lives and also leads to substantial material damage. Usually the detection of fire is relatively quickly, because in mines CO-detection systems are used. However, it’s very important to take prompt decisions when a fire occurs in a mine. The most important thing is not to allow for the development of a fire. The analysis of changing in the mass of burned coal and prediction of fire gases temperature are conducted in the article. These analysis show that the best way to reduce the fire development is reducing significantly the volumetric airflow through the excavation with fire.

Contribution to the assessment of mercury emissions from burning coal waste dumps

Abstract: Coal mining waste dumps are responsible for the emissions to the atmosphere of gases such as: carbon monoxide, carbon dioxide, sulphur dioxide, hydrocarbons and the highest emission intensity occurs on the burning coal mining waste dumps [1, 2, 5, 6]. In the hard coal mining and processing waste dumps very often combustion can be observed. The fires are a direct outcome of applying inadequate dumping technology and depend on the physico-chemical properties of the dumped waste rock. The conducted analyses of the burning coal mining waste dumps leave no doubts: the burning dumps are also the source of mercury emissions. Unfortunately, so far in Poland not even estimations of the mercury emission level from this type of objects have been conducted and, thus, the scale of the problem is not known. The article presents the results of preliminary ratings scale problems as well as an estimate of annual mercury emissions from burning coal mining waste dumps in Poland.

Deepening the 8 shaft of „Jankowice” coal mine as a perspective of developening the mine after 2020

Abstract: The 8 shaft is the fundamental element of a mine model and putting it into operation would make it possible to eliminate the 6 shaft including the infrastucture and unblock resources being trapped in a protective pillar. The process of deepening the shaft with 8,5 m diameter was started in November 1987 and finished in August 1991. The shaft has been 731,76 m deep – from the shaft framework, simultaneously a single-sided inlet at the level of 250m and double-sided inlets at the levels of 400 m, 565 m and 700 m has been done. In September 2004, the mine obtained permission to shaft hoisting motion in the eastern range whereas in the first half of 2006 in the western range. In 2008 the contractor for the conceptual project of building levels 880 and 1070 m as well as technical and technological project of shaft deepening to 1103,7 m level was chosen. In November 2010, the realisation of technological excavations indispensable to 8 shaft deepening was started. These actions were finished in January 2013. Next, the work was ongoing, which was connected with a large-diameter hole drilling from 880 m level to 731,76 m level. Currently, the mine is performing the contract “Deepening the 8 shaft on measuring distance from 731,76 m level to 1103,7 m level, together with making a shaft housing and two double-sided inlets on 880 m level and 1070 m level, and also inbuilding shaft reinforcement for the Coal Mine joint-stock company, Branch Jankowice Coal Mine”.

Effectiveness of air conditioning systems in coal mines

Abstract: It is difficult to ensure stable parameters of microclimate by means of ventilation and air-conditioning in underground excavations. In the nearest future a further deterioration in ther-mal hazard in Polish coal mines can be expected as a result of mining at deeper and deeper levels. The aim of this article is to present used methods of climatic conditions control and to indicate errors in design. There are natural and technological heat flux sources in mine airways. High air temperature and humidity lead to worse climatic conditions. It results in slowing down some functions of a human organism, such as perception, concentration and attention. This unfavorable effect of air temperature and humidity on human body is known as thermal hazard. Problems connected with design of ventilation and cooling systems in underground mines are becoming more and more important.

The industrial revolution in Europe, in the former polish lands and in upper Silesia

Abstract: This article describes the social and economic changes in Europe and Poland in the 18th and 19th centuries. It presents the period of the industrial revolution in cause and effect categories. The article discusses the most important technical discoveries and their influence on the development of industry (textile, coal, metallurgy), agriculture (large-scale mechanized agriculture) as well as their indirect impact on social change (urbanization, development of industrial districts, inflow of the rural population into cities, liberation of peasantry, formation of new social classes- the middle-class, factory owners, laborers). The article also demonstrates the geographic diversification of the industrial revolution, with Great Britain and the USA leading the way. The geographically diversified industrial revolution also included the former Polish lands (i.e. Polish territory belonging to three different countries, the economies of which were completely different from one other – Germany, with a thriving economy, Russia which remained far behind in terms of innovation, and Austria with a slow-growing economy) with its developing Upper Silesia region.

The risk of entrepreneur mining activity related to hiring employees

Abstract: Managing a business is linked with various risks. One of the most important, resulting from the rules of the labor law, is the risk associated with hiring employees. It concerns legal systems all democratic countries. Its level is also increasingly associated with a wider and more effective protection of freedoms and human rights, including employee (eg. the right to safe and healthy working conditions, the right to privacy, protection of personal data). In Poland, due to historical circumstances and dynamic changes in the period of political transformation, in some respects this risk is of specific character. In extreme cases, the level of this risk can decide about economic prosperity of implemented business venture. The biggest problem is the fact that in the case of different types of risk, employer has little opportunities to minimize them. Given the level of threat and a well-developed worker protection, the situation has particular importance in the mining industry. The purpose of this article is to draw attention to this issue, because it seems that in a democratic legal state, protecting the employer in this area should be higher.

Numerical simulation of dynamic effects of a rockmass shock on a mine working

Abstract: The paper presents results of numerical modeling of the effects of dynamic loads in an area of a mine working resulted from a rockmass shock. The assessment of changes affecting the working area has been evaluated with use of an anisotropic ubiquitous joint model. Computer simulation covered two main stages: static simulation, which includes assessment of the destruction state of rock structure in the surroundings of the mine working, and dynamic simulation that includes additional loads of the rockmass, which surrounds the working and its support in the result of the shock. Conducted numerical calculations demonstrated that increased loads resulted from a rockmass shock results in significant increase of destructions in the rockmass and increased deformations of the working profile.

Social preferences of directions revitalization in a selected mining area of Polish-Czech borderland

Abstract: Mining activity causes negative changes in the environment, which are most frequently referred to as mining damage. The major effects of mining activity include deformations with secondary effects, discharge of saline waters from mining plants’ drainage, mining waste, areas requiring reclamation and management, methane emissions from mines, emissions of dust and gases. It should be emphasised that mining damage has a strong influence on the psyche of people inhabiting the degraded areas and can cause the sense of hopelessness, loneliness and helplessness, which results from living in such a place. The appearance of degraded areas is closely related to the change of industrial society into post-industrial society. These changes refer not only to economy and economic activity, but also to spatial standards and all kinds of lifestyles. These new forms of activity should become a priority for degraded areas. In post-industrial society the spatial demand for production purposes is lower, whereas for services, consumption and recreation this demand is higher. Phenomena related to the unfavourable effect of mining activity are particularly visible in the border area of the Silesian Province (Poland) and Moravian-Silesian Region (Czech Republic). The article presents a discussion of the results of studies the aim of which was to become acquainted with the local community’s opinion on the preferred directions of post-mining areas’ revitalization. In the conducted studies the opinions of different social groups according to their occupation, age and education have been analysed.

The 5 Whys method as an element of maintenance management in a coal mine – an implementation attempt

Abstract: Coal mines in Poland increasingly often introduce quality management systems, which oblige them to adhere to the rules of constant improvement of main and auxiliary processes. Constant improvement in organisation can be achieved through a number of quality management tools and methods, which effectively enhance the efficiency of organisational processes. Nonetheless, quality management tools are massively underused in Polish coal mines. The author of this article would like to present a possibility of applying select quality management methods in a coal mine, which would be innovative for the company and introduce a new quality to the processes conducted. One of the more important auxiliary processes in a coal mine is the maintenance process. The effectiveness of this process depends on a number of factors, such as: keeping technical assets in a state of constant readiness, efficient failure elimination, and reducing the stoppage time due to breakdowns to an absolute minimum. The priority of the maintenance process in a coal mine is to keep in a state of readiness the machinery and equipment involved in the extraction line. A high readiness level can be maintained by, among others, reducing the failure elimination time. This is especially important due to the fact that the extraction line is a chain of machines involved in the process – a failure in one of the machines automatically stops the operation of all the others. That is why this article will present the implementation of a selected quality management method in order to improve the efficiency of the maintenance process in a coal mine. This should make it possible to identify the primary causes of prolonged stoppages and find an optimal solution to the problem.

Correlation of occurrence of surface buildings damages with mining tremors by examples of Piast coal mine in the years 2014-2015

Abstract: Mining tremors are one of the most important side effect of mining operation from the point of view their influence on infrastructure located on the surface of the mining area. Protection of surface and buildings located on the surface is one of the requirements to fulfil by present-day coalmines, because each mining operation is awkward for users of buildings. Piast Coalmine has operated coal seams for over 40 years, that is reflected in a large number of high-energy tremors and thus the vibration that may affect the condition of surface buildings. In the paper the reality referring to the number of examples of high-energy tremors is shown, that may cause mining damage to surface buildings in correlation with the amount of damage reported and the cause and effect relationship between the tremor and the reported damage.

Assessment of technical condition mining machines based on the criterion of the Weibull distribution

Abstract: : In exploitation of machines one of the prior parameter is dynamic condition of an object. The most popular method of giving results about dynamic condition is observation of residual processes. Especially dynamic residual processes are carriers of diagnostic information. measurements of vibration and noise of working machines provide knowledge about dynamics of a evaluated machine. Long-term knowledge and experience allowed to create diagnostic procedures. In mostly devices created in industry, procedures are written in standards ISO 10816 and ISO 7919 which allows effective diagnostic and optimal management of devices. Applicability of this standards is most popular, but there also appear devices which parameters forbid their applicability. To this devices can qualify some of used in underground mining. Giving a diagnostic mark for a longwall shearers, scraper conveyors and many of the others devices being in technological sequence, application of mark spheres compatible with ISO 10816 and ISO 7919 is incorrect. In diagnostic evaluation this kind of a machine we usually use analysis long time trends. Determination acceptable levels of vibrations are getting in heuristic way, by observation a development of a damage to an emergency state. In article there is presented methodology of giving a diagnostic mark about machines which uses models of degradations of a device, based on Weibull analysis. Presented method were used to gave real marks of vibration machinery and equipment for underground mining in one of the coalmine. Conduction of analysis showed a more effectiveness of a presented methodology.

Abstract: Inseparable element of the lime production process is pipeline transport of hydromixture which arises from rinsing of stones. Such hydromixture is a finely-granular solid phase and the water that serves as a carrier of the solid phase. At the end of the transporting process the water is recovered in order to recycle it for re-circulation, and the solid phase is deposited in dumps or in the sludge tanks. Hydromixture clarification process through the process of sedimentation, is difficult due to the large amount of solid particles with a diameter less than 2 mm. In order to improve the efficiency of sedimentation process we added polymer additives called flocculants. They allow the formation of flocs by binding together fine particles into larger agglomerates, which are under the influence of gravity and fall intensively to the bottom of settler tank.

Abstract: The paper deals with solid-liquid limestone slurry with a high solids concentration, which appears widely in a mining and civil engineering industries. Experiments performed in the paper deal with influence of solids concentration on the shear stress. Solids concentration various from 20% wt. to 35% wt. which is most suitable to industry. The main objective of the paper is to determine the flow curves for high solids concentration of slurry at limestone factory and to fit the proper rheological model. The paper proves that most suitable model which fits measured dependence of shear rate on the shear stress is the Herschel-Bulkley rheological model. The exponential increase of shear stress and plastic viscosity with increasing the solids concentration is demonstrated for high solids concentration of limestone slurry.

Abstract: Measurement System Analysis is a part of “Measure” phase, which is a structured project management approach. This approach consist of the following steps: Define, Measure, Analyze, Improve, Control – “DMAIC” and is a path to resolve production problems based on Lean Six Sigma methodology. This method has been presented by using of computer aided statistical software – Minitab – which is a most common statistical software, used by Green or Black Belts. As a Master Black Belt I faced to the problem of lack an appropriate explanation of using it by the Belts – which contributed by implementation of a proper training program. Measurement system analysis in this program, is divided by Attribute Agreement Analysis, which is analysis of attribute data, and Gage R&R – analysis for continuous data. Therefore it is very important to understand differences between attribute and continuous date and their main metrics. Understanding data types, allowed to explain components of measurement errors. This base knowledge is a foundation of measurement system analysis and going further – base knowledge of each Green or Black Belt.

Abstract: The study presents issues related to the motivation of human action and its shaping. The issues are presented from the point of view of psychology, sociology, management science and cybernetics. It was found that in the application of appropriate stimuli may affect motivation to change and consequently the change in quality of performance. The common denominator of these areas of study is the conclusion that the motivation may be the result of the conditions of information or energy. Maslow, human motivations, addicted from needs. He introduced the so-called pyramid of needs, from which it follows that the greatest impact of human motivations are the needs of an energetistic nature. But the Herzberg in his two-factor theory of motivation found that motivations are the result of exposure to man, so-call motivators such as stimuli (incentives) of the informative nature. At the same time he provided the conditions which made the effectiveness of these motivators. Mazur introduced the man as an autonomous system and describe the processes that determine the motivation of action. He said that the man, as the system must be able both to retrieve from environment as well to place on in to the environment, the information and energy. This means that the motives of human actions can have only informative and energetistic character, what largely corresponds with the results of sociological research. Kossecki linked motivations of human activities with distinctive social norms and depends of the human norm type, he found that motivations can be informative, energetistic, or mixed. To similar conclusions is reaching when it is depending the type of motivation of man's relation to the basic categories of social existence, given by Koneczny. Using the principles of transmission of information it has been shown that the efficiency of the control depends on the motivation. People with the energetistic motivation are more likely susceptible to control. In the discussion are presented examples of control in technical systems, typical for the problems presented in the work.

Adaptation of truck crane to other applications in the light of applicable standards - case study

Abstract: The article discusses the issue of the mobile cranes, used primarily for moving cargoes to other needs, especially related to transport people. The applicable law in the European Union (in particular the New Approach Directives), imposes a requirement on technical equipment to meet the relevant conditions for the protection of health and safety. Marketing authorization may be granted only to a machine which does not pose a threat or when risk levels during its use are known and acceptable. The levels are defined by European standards which, in this case, are called harmonized standards. If a device can have various applications, it must meet the requirements of various harmonized standards. This often forces the need to make structural changes to them.

The evaluation of environmental effects of building thermal insulation

Abstract: One of the strategic objectives in Poland and other European countries is to improve energy efficiency. This paper aims to present a method for evaluating environmental effects of the pro­ject associated with thermal insulation of the building including the assessment of sensitivity of selected variables. To evaluate the environmental impact the methodology of life cycle assessment (LCA) was used. Both the environmental costs (increased burden on the environment) related to ther­mal insulating materials and environmental gains (reduction of environmental load) resulting from the reduction of energy demand for heating in the use phase of the building, were taken into con­sideration. The options were included with regard to the type of the external wall, heat source used in the building, the type of thermal insulating material, and the climate zone in which the build­ing is located. For each studied variant a positive effect was obtained - reducing the burden on the environment as a result of thermal insulation.

Mercury content as a part of a multi-criteria analysis of investment potential of post-mining areas

Abstract: The dynamics of economic transformation in Silesia caused that a lot of post-mining areas were left undeveloped in the areas related to the mining industry. Lack of information about the degree of degradation, key ecological features, and often unclear ownership status means, that the­se areas are managed by investors reluctantly. Each degraded area has some potential and it may be a source of new opportunities. It is necessary to have knowledge about them to determine the direction of re-used. A model of the computer system for decision support in choosing a strategy for redevelopment of post-mining areas is created. Model is based on a relational database which col­lects information on the multi criteria degraded areas, including environmental data identifying land pollution by harmful substances and hazardous, such as a mercury. The paper presents the re­sults of the mercury content in mining wastes, which were deposited in the landfills and in the soils of post-mining areas.

The challenges facing companies after the revision of ISO 9001: 2015

Abstract: The norms form the ISO 9000 series are among the best known standards published by the International Organisation for Standardization ISO. They contain guidelines and indicators for companies and organisations that wish for their products and services to continuously meet the clients’ requirements and to constantly improve their quality. Since its first publication in 1987, the standard has seen a few significant modifications with the most significant ones made in 2000. In September of 2015 the International Organisation for Standardization ISO published a new version of the ISO 9001 standard. From this date onward a three-year transitional period needed by every company to adjust their system to the new standard. 96000 certificates were issued in Poland in 2014 confirming conformity with the ISO 9001 standard.

Barriers to effective management of complaints - case study

Abstract: Currently, among the manufacturing companies increasing importance of gaining know­led­ge, which often is seen as a competitive advantage in the rapidly changing environment. The most valuable source of information is the customer, both external and internal. It was he who plays a key role, as it allows the company to generate a profit. Hence, it is important to meet the stan­dards, which often are very difficult to implement, especially considering the qualitative aspects of the automotive industry. A manifestation of non-compliance is complaints. They are usua­lly unwanted by the company, but in literature you can find publications, where requests from clients are treated as an opportunity for improvement and development of the company. To effe­cti­ve­ly manage complaints and process the acquired data into information and then into knowledge is indi­spensable to introduce a suitable system. The authors analyzed an example of complaint ma­na­ge­ment system, where, based on his experience and theoretical knowledge have identified barriers to its effective functioning.

Application of a process approach for the needs of supporting management of information and technical resources in crisis situations

Abstract: The subject of this article is to point out the problems of the functioning of the emer­gen­cy services in crisis situations. The problem and the proposed measures and possible solutions are pre­sented in the article on the example of a particular object of research, which is the airport Ka­to­wi­ce - Pyrzowice. Due to the international nature of the activity of the airport, its po­ten­tial sus­cep­ti­bility to the occurrence and effects of all kinds of emergency situations is con­si­de­ra­ble. Stringent legal provisions governing the activities of airport both in terms of safety for the pur­po­ses of operating, as well as civil aviation security are oriented to minimize both the risk of a crisis and its potential effects. Joint activities require effective co­ordination of all services at all levels of the level of functioning of the administration complex. The paper proposes a solution-oriented mainly on the improvement of com­mu­ni­cation between participating in the activities of emergency entities. This solution should provide co­ordination of emergency services at the level of the transmission of single, accurate information to all involved formation.

Economic and environmental benefits resulting from the changes of standards for the values of heat transfer coefficients in buildings

Abstract: Final energy consumption in the residential sector in Poland in relation to final energy consumption in all sectors of the economy stands at about 30%. The thermal insulation of building walls, constructed in order to reduce the energy demand of buildings for heating is economically justified. Hence the amendment of legislation in reducing the heat transfer coefficient of various elements of the building is most desired. The paper examined the economic and environmental benefits arising from changes in the value of heat transfer coefficient in the legislation. Normative values of this coefficient to be implemented in 2017 are justified economically and ecologically in Polish conditions. The payback periods of economic costs related to larger thicknesses of thermal insulation (from the requirements for 2014 to the requirements since 2017) emerge within 2-8 years, and environmental costs in the range of 1-5 years, depending on the heat source used in the building.

Capabilities and limitations of decreasing mercury load in polish bituminous coal in the production process

Abstract: Mercury is one of the most toxic elements contained in bituminous coal. Poland is considered to be the biggest Hg emitter of European Union because of significant carbonization of its economy. It is possible to greatly decrease the mercury load in the production processes of hard coal. Poland’s problem is the large share of raw coals use in power engineering. The Hg content in raw coal remains unchanged. Increasing the range of coal enrichment in polish collieries is feasible but difficult because of current market situation. The reduction of Hg content in bituminous coal could be possible by addition of product of larger granulation to average the fuel quality. However these coals are traditionally used for household heating.

Keizen system implementation in an automotive company – case study

Abstract: In the 21st century one cannot avoid combining the modern model of production management with the philosophy of continuous improvement. This is particularly visible in the automotive branch. The automotive market is characterized by very high dynamics, constantly increasing requirements from customers as well as requirements resulting from the changing (stricter) legal regulations: fumes emission standard, safety level, restrictions in the use of various kinds of materials etc. To meet the demands and ensure their enterprises’ competitiveness on the market, producers are introducing modern, proven methods of management and organisation. They willingly base their activity on Lean Management principles. The major tools (co-dependent and mutually supportive) of this method include: VSM, 5S, TPM, SMED. However, transferring Japanese management systems into European conditions alone does not guarantee success. This results from the fact that Far Eastern concepts originate from the culture-bound Keizen philosophy, which is based on team work. The major pillar of the Keizen philosophy is engagement of all the employees in the improvement process, which contradicts lower-level employees’ individualism, so deeply rooted in Western culture. The strength of Keizen lies in the fact that while using the existing tools, the developed technology as well as the knowledge and experience of employees, it does not require high expenditures, changing an enterprise on a step-by-step basis. This gives a considerable advantage over the Western approach, mainly based on innovative, expensive activities, which require the engagement of specialists and lead to big, rapid changes. In the article a manner of implementing in an automotive company have been presented.

Urban traffic problems of kaliningrad and their solution

Abstract: The main cause of degradation of our cities is a "clash of cities and cars". In Kaliningrad over­come the critical threshold of motorization around 300-400 cars per 1000 inhabitants. This situation is characterized by traffic jams, road accidents and environmental deterioration. To over­co­me the crisis should be developed and implemented measures of transport policy in two areas dis­cussed in the article. Without their introduction the town cannot become a city „liveable".

Application of GIS systems for delimitation of degraded areas of small cities and rural areas

Abstract: The paper presents the results of research on application of GIS systems for delimitation of degraded areas in smaller municipalities. During the analyses it was found out, that the di­stri­bu­tion of population of smaller municipalities is uneven as most of the areas are covered by forests or corn­field. This increases population on smaller housing areas. From the point of view of socio-eco­no­mic indicators related to the unit of area of the land, it interferes the measurements. On the other hand, due to lower number of inhabitants comparing to larger cities, taking some of the indicators that are standardised to „per 100 persons” as they are, may also interfere the results and distort the real situation. This paper is an attempt to handle these dilemmas.

The use of Kano model for the classification of the elements of product quality

Abstract: The article presents a case study of the use of the Noriaki Kano model, which allows the iden­tification of the characteristics of the perfect product from the perspective of a potential cu­sto­mer. One of the basic assumptions of the Kano model is the variability of customer requirements, which with the passage of time and copying attributes of a product by competing companies, so-cal­led "stunning" factors become common and become expected attributes, then the desired factors, and in the final phase the discouraging factors. The studies of features, of the perfect product we­re carried out in the company of processing meat and vegetable. There were identified four groups of features: attracting, standard, one-dimensional and neutral. Based on obtained data the­re were modified packaging and changed areas of allocating given type of assortment on the mar­ket.

Spatial surrogate for air emissions from small residential combustion – analysis using scarce top-down estimates

Abstract: This paper presents methodology for obtaining 'first step' spatial surrogate for disag­gre­ga­tion of air pollutants' emissions determined using top-down approach. Considered sector was small residential combustion due to its importance in emission budget, also potential health thre­at­en­ing. However our analysis is not flawless due to partial loss of information connected with lo­ca­tions, can be effectively used as specific method for determining of spatial outliers. Simplified ap­proach shown in this paper uses values derived from gridded population density as downs calling fa­ctor for air pollutants' emissions. We determined three potential regions that should be treated se­parately to obtain independent – ‘regional” emission surrogates.

Autocorrelation occurrence in measurement results of regularly sampled sound levels in environmental noise risk assessment

Abstract: The determination of the uncertainty of measurement is a necessity of each control procedure. According to the limitations of the method of uncertainty of measurement determination; (recommended in the Guide of the Central Office of Measurements prepared under auspices of the International Bureau of Measurements); the necessity of analysis of time links of instantaneous sound level LAi values, which are used for calculations of the controlled noise indicators, occurred. The authors considered the problem of an autocorrelation occurrence in measurement results of the regularly sampled sound levels. The indispensable identification of the autocorrelation function for the controlled variability in the calendar year of equivalent sound levels L Di, L Wi, L Ni, I = 1,2,. .,365 – was presented. The necessary correction of the up to now solutions of uncertainty assessments - by determining the effective number of uncorrelated control observations n eff, depended on the autocorrelation function – was indicated. These considerations were supplemented by the numerical example illustrating possible differences in uncertainty assessments in the estimation of the controlled noise indicators values.

Analysis of influence of clevises on functioning of friction joint

Abstract: The paper presents the results of research on influence of clevises and their yokes on functioning of friction joint used in mining housing of corridor excavation. Apart from the construction joint, the main role of the clevis in friction joint is ensuring sufficient downforce among working profiles, which is related with the necessity of ensuring axial load in threaded joints. For this reason there was performed research on whole clevises and their yokes concentrated on determining the value of the load, at which they get permanently deformed. These deformations are the main reason for non-axial load of threaded joint. The research was done on the most commonly used constructions of clevises and the reinforced version of SDO29 clevis. The results prove that the clevises have crucial impact on functioning of friction joints and safety of work of the housing.

Process map as an innovative tool of quality optimisation of the production process

Abstract: Process mapping is of significant importance in quality management as it allows us to precisely analyse the processes going on in the organisation and, based on it, conduct an analysis of the critical points in the production process using selected quality management tools or methods. Organisations constantly search for new, innovative solutions and methods which can be used to increase their efficiency and product quality. An important measure taken by today's companies is the identification of causes of the defects recorded in the production process, and analysis of returns from external clients. This makes it possible to reduce production costs and increase the company's reliability in the eyes of the client. However, to achieve it, the company first needs to map the process. The article presents improving the production process of a vibrating screen manufactured by a company which produces machinery and equipment for the mining industry, using a process map. The analysis conducted made it possible to propose corrections and changes to the production process, which increased the efficiency of the analysed product.

Example of use of quality tools in the improvement of maintenance process

Abstract: The article presents the results of observational studies conducted in one of Silesian production companies. The research was aimed at improving the maintenance process and focused on the analysis of utilization of working time by the employees. The measurements were taken for three randomly chosen persons. The most important actions performed by the employees were identified and assigned to effective time – spent on everyday duties connected with maintaining the functionality of technical equipment, auxiliary time – dedicated to preparatory and administrative activities, and ineffective time, during which the employees performed actions not connected with their work. Among the ineffective and auxiliary actions those which took the longest were separated. In order to reduce their duration, the 5-Why method was used. It allowed us to identify the causes responsible for the overly long duration of auxiliary actions. As a result of the analysis conducted, corrective measures were proposed aimed at reducing the duration of those actions along with a system for their assessment, which should lead to an improvement in the efficiency of maintenance department employees.

Abstract: The well-established tool to help manage the company's ERP system. However, due to the division of the production process of co-operate with each other to form a network of logistics. In general, these networks do not have an identified organization. Individual enterprises are completely autonomous in establishing new relationships. An important problem of the management is the dynamics of such networks. Due to the exchange of information between companies this network shows inertia. Prevention of inertia increase the competitiveness of companies in the network. In response to this problem, presented in the publication, is to control a network of enterprises using the method of ATP. We show that this can be applied to existing technologies, information technology – ERP systems supporting the management of enterprises. This allows to improve the manage with possible small costs of reorganization and implementation of new technologies.

Weathering indices variability of contemporary odra sediments and its tributaries

Abstract: Chemical weathering indices are commonly used for characterizing weathering profiles and evaluating degree of weathering process. Their values allow to point at non-weathered source rock composition. Using study results of Odra and Warta drainage basin sediments, there was made a try to define variability of chemical indices in this country area. Among applied indices the most important role have Weathering Index of Parker (WIP) and Chemical Index of Alteration (CIA), thus them was given the most attention to. In order to better reflecting the intensity of weathering there were used additional indices, sensitive to the slightest geochemical changes. Vogt’s Residual Index (V), Chemical Index of Weathering (CIW) and Plagioclase Index of Alteration (PIA) were calculated. Study results let to evaluation the weathering intensity in the all study area and to indicate factors, which are in charge of this process. Lithology, climate, flow magnitude and region morphology have an influence on the values of weathering indices.

First step to urban mining. Restoration of gas wells in municipal waste deposits and reactivation of gas production

Abstract: There are two themescombined: first, there are gas wells in municipal waste deposits with leakages which don’t deliver usable gas anymore and second, there are abandoned municipal waste deposits closed in the 1980’s with any sealing neither at bottom nor on top. Both, abandoned municipal waste deposits and waste deposits with leakages in their gas wells, are sources of air pollution and common to both is the lack of money to stop this pollution. The aim of research team of THGA is to find cheap solutions to stop the contamination around municipal waste deposits. Gas wells in municipal waste deposits normally are filtered from the bottom to the top over their full length. In the top layers the organic waste reacts with oxygen and these parts are inertised in a short time. This will result in leakages between the surface and the well. From that time the well will suck air from the surface but no more gas from deeper layers. Power plants cannot work anymore because of the bad quality of the gas. In a laboratory test the restoration of such wells with a special kind of foam was tested and improved. Later in several wells of Celje municipal waste deposit (Celje, Slovenia) leakages were located in sucking tests. The filter lengths with leakages were foamed and after this restoration gas of higher quality was sucked. In the last century nearly every village in Germany, but not only there, had have their own municipal waste deposit. There was no soil or groundwater protection or a system to suck any gas. By the first “LAGA Merkblatt – Die geordnete Ablagerung von Abfällen” (a regulation about waste deposits in Germany) from September 1979 a system with a new type of landfills started. This type contains a base of low permeability, water and gas drainage system, as well as surface covering. Concentration on a few great landfills began and a lot of old landfills were abandoned. These old landfills were covered with soil and most of them still exist in this form in the landscape. Unfortunately these landfills still show chemical reactions. They still produce waste water and landfill gas. So they are contaminating the groundwater and their gas production still destroysthe vegetation on their surface. Methane and carbon dioxide are polluting the atmosphere. But most authorities don’t accept this problem because these landfills have been closed for more than 30 years, and therefore the landfills are expected to be inert.

Analysis of the effects of driveway shape on the efficiency of roadside noise barriers

Abstract: Roadside noise barriers are the most common measure for reduction of traffic noise around housing. In existing traffic systems the necessity of noise reduction through acoustic screens often conflicts with existing driveways and local roads. Proper design of driveways allows for increased effectiveness of the barriers and is usually crucial to the success of the undertaking. Leaving multiple openings within the barriers leads to decreased efficiency and the occurrence of acoustic glimmering. This article presents the efficiency-decreasing effects of leaving discontinuities within the noise barriers and appropriate solutions for noise reduction around driveways.

Current-carrying capacity of mining flexible cables at intermittent and short-time duty

Abstract: The basis for a selection of conductors’ cross section of mining power cables is the continuous current carrying capacity, resulting from continuous running duty of motors. Polish Standard for rated parameters of motors determines, besides the continuous running, other types of load that can be described numerically, graphically or by selecting one of the predefined types S1 to S10. In case of intermittent, short-time or variable load, the selection of the cable cross-section based on the continuous carrying capacity may lead to unjustified overestimation of cross section or excessive temperature rise of the cable insulation. The methodology for determining the intermittent or short-time current carrying capacity has been described in the article. Results of current carrying capacity calculations for intermittent load and of the time of cooling to an ambient temperature have been presented.

Computer simulation of dynamic loads in the selected constructional nodes of a boom–type roadheader body when carrying out the mining process

Abstract: Boom–type roadheaders represent the fundamental group of working machines used in underground hard coal mining for drilling of dog headings. The cutting process, especially of rocks with low workability, is causing strong dynamic loads likely to lead to low effectiveness of a roadheader‘s work and to the failure of its key subassemblies due to significant loads exerted on them. The identification of dynamic states of a roadheader body when carrying out the mining process – a machine treated as a complex dynamic object – is therefore of fundamental importance in the context of designing such machines and for optimising the parameters of working processes performed by them. The article presents the selected results of computer simulations of R-130 roadheader body dynamics when carrying out the cutting of rocks with differentiated workability. Such situation is common in drilling dog headings in rock mass with a layered structure, where easily workable rocks (such as for instance hard coal) are accompanied by rocks difficult to work with (for example sandstones). The examples are presented of dynamic characteristics of the drive of boom deflection mechanisms which are responsible, apart from the drive of cutting heads, for performing the cutting process effectively. The sensitivity of the boom deflection mechanism drive to the cutting process implementation conditions was also established.

Stereovision methods in granulometric analysis

Abstract: Stereovision is a way of three-dimensional image acquisition based on the imitating the operation of the human visual system. The article discusses basic stereovision principles and the concept of application of this method to the granulometric analysis of the surface layer of a particulate material stream on a moving conveyor belt. Through the use of of the belt movement it is possible to design a simple stereovision system with a single high resolution camera, recording two pictures within a short time interval. There have been presented some results of preliminary tests performed on a laboratory stand. There have been also described the advantages and disadvantages of stereovision methods compared with other types of three-dimensional images acquisition methods. The main advantage is a low hardware complexity, relatively low cost and high resolution of recorded images, but the main drawback - high computational complexity for images involving a large number of particles (fine granulometric classes), associated with the need to identify the corresponding points in the sequence of two successive images.

Simulation model of a radiometric density meter

Abstract: Radiometric density meters are widely used in the industry to monitor different technological processes also in coal preparation such as: Heavy-media separation, Jigging, Flotation. Operation of the radiometric density meters is based on the method of gamma radiation absorption. The measuring head of the radiometric density meter consists of a radiation source and a detector usually in the form of a scintillation counter. The output signal from the detector is sequence of pulses which is always a stochastic signal with Poisson distribution. These pulses are often counted by a counter being a kind of a low-pass digital filter. The relation between the measured medium density and the mean intensity of registered pulses is theoretically exponential. In the paper there has been presented a simulation model of the radiometric density meter. There have been described the measurement method and given densitometer model equations. Example simulation results have also been presented in a graphic form.

Sets of machines and systems for sinking the II underground coal storage bunker in the JSW S.A. KWK “Pniówek” coal mine

Abstract: The article presents the sets of machines and systems for sinking the II underground coal storage bunker at the level of 830 m in the JSW S.A. KWK “Pniówek” coal mine and the analysis of the conditions related to the sinking of the bunker. The small distance between the first bunker and the newly built bunker, that is only 30 m, turned out to constitute a technical difficulty. This distance resulted in the withdrawal from the traditional method of driving using explosives and forced a proposal to apply a new technology of driving without the use of explosives as well as the selection of machines and devices. The innovative solutions that have been applied had to guarantee that the structure of the existing tank I would remain intact and that the space between the elements of the concrete enclosure would be completely filled. The sets of machines and devices related to the construction of the bunker have been compared depending on the selected variant of sinking technology. Based on the conducted analysis of the conditions related to the construction of the bunker and the sinking technologies, the use of machines and devices fulfilling the specified requirements has been proposed.

Determination of static characteristics of multichamber flow flotation machines

Abstract: Determining the static characteristics of the enrichment process in industrial flotation machines is a difficult problem because of the influence of many parameters on the process. It is assumed that a parameter which contains information about the factors affecting the process is the velocity coefficient k of the flotation particles. This parameter is characterized by distribution of the particles flotability f(k). The function of this type is obtained based on the course of the kinetics of the mass feed components in the batch flotation process. Determining a function f (k) is carried out indirectly by a mathematical model based on the course of flotation kinetics m(t). The determined parameters of the kinetics model are also the parameters of the model of the distribution density function of the coal particles flotability. Based on previous works has been shown that the feed heterogeneity can be well characterized by the model of the triangular distribution function f (k). Using the distribution of the particles flotability it can determine the distribution of the ash content depending on changes of the coefficient of the flotation velocity. On the basis of these dependencies can be determined the static characteristics of the flow flotation machine. The static characteristics of single and multi-chamber of the flow flotation machine in the paper have been presented. Obtained on the basis of simulation the static characteristics of the concentrate recovery and ash content in the concentrate depending on changes in the intensity of the air are similar to the characteristics determined by the authors based on the research of the industrial flotation machines. Knowledge of the characteristics of the density of the fractions distribution together with the distribution of ash content will allow a better assessment of the phenomena occurring in the enrichment process. The static characteristics of the single and multi-chamber flotation flow machines determined on the basis of these models can be used in the design of systems of the process control of the minerals flotation.

Carbon footprint levels analysis for the world and for the EU countries

Abstract: The increase in the world population and global economies causes a permanent increase in demand for electricity. The basic fossil fuels for the electricity production in the world are oil, coal, natural gas and other such as: nuclear power and renewable energy. Burning fossil fuels causes greenhouse gas emissions, which contribute in varying degrees to global warming. The aim of the article is to analyze the carbon footprint for the world and for the EU countries. The article contains the characteristics of the concept of the carbon footprint, which is the total amount of CO2 and other greenhouse gases, e.g. methane and nitrous oxide in relation to emissions resulting from the product life cycle, including its storage and disposal. The carbon footprint is quantitative and universal indicator, which can be calculated for the enterprise, a specific product, service, process, organization, country or region. The paper also presents a comparative analysis of this index for different countries in the world and in the EU. Calculations of the carbon footprint in total and per capita are shown which significantly differentiates assessment of world economies in terms of emissions.

Safety underground tourism routes in ZKWK "Guido" – proposal for survey

Abstract: ZKWK "Guido" which is part of the Museum of Coal Mining in Zabrze is unique in the world. In addition to presenting the monuments of mining technology on the surface of the earth provides tourists underground roads. At present ZKWK "Guido" provides several underground tourist routes. Most are located on level 170 (the work of the miners at the turn of the century in the area of Silesia, the hazard of mines, mining traditions) and 320 (excavation maintained in a position as close as possible to the original). Level 355 (opened on 4th February 2016 years) can be visited either during the so-called "szychta" (visitors in work clothes with a guide-miner perform simple jobs mining), or as so-called "darkness of the mine" (visitors receive a personal lamp and visit the route in the dark). The aim of the article is to propose a survey on the safety of tourist routes in the mind of the visitors themselves, together with the results of pilot studies carried out in ZKWK "Guido." For this purpose, a special questionnaire (as contained in the work), which included questions concerning three main areas: general security (including the respondents were asked about the signs and lighting routes, elements that may constitute a danger to the public, the symptoms of malaise, behawior guide), events potentially dangerous (trips, falls, hitting his head and other dangerous occurrences), and the satisfaction of tourists (satisfaction with tours, attractions, sense of security, other comments on safety). Based on the developed survey was conducted a pilot study in ZKWK "Guido" among 100 randomly selected visitors to the different routes in underground mines. The test results are provided in the charts, taking into account also the gender, age and education of respondents. The survey was anonymous, and its fulfillment voluntary. The results of the pilot survey should allow for refinement of the survey, the results of which can become an indicator of the problem areas, the safety of tourist routes in the feelings of visitors, require attention from policy-makers at the Museum of Coal Mining in Zabrze.

Influence of frequency innverters on operation of induction motors in mine environment

Abstract: The paper contains analysis of cooperation between induction motors with the intermediate frequency inverters that supply them. In the mine environment, parasitic elements of the cables, parameters of the filters’ elements, and a method of control over inverter transistors have an impact on the regime of motors fed by the intermediate frequency inverters. An important feature of such a converter is that it is not a source of sinusoidal voltage. Deformation of voltage output is a result of inverter transistors being switched up multiple times with pulse – width modulation (PWM) control. Large steepness of the converter output rising voltage is related to switching of the transistors. The steepness reaches values of up to a dozen or so kV on μs. Such a large steepness of output rising voltage can cause passage of large capacitive currents. The paper discusses also the influence of the parameters of individual cables on values of the overvoltages and earth leakage currents. Various ways to limit this negative phenomena (overvoltage, the earth leakage current) are also discusses in the paper.

The influence of analog low-pass filtering in the measurement circuits on the signal parameters

Abstract: Measurements of various physical quantities are usually performed so at first instantaneous values of the measured quantity are converted into instantaneous values of the electrical voltage, and then this voltage signal is transmitted to the analog-to-digital converter through the measurement channel. However – in the measurement practice – it happens, that inadequate attention is paid to the issues of the signal filtering in measuring channels, or this filtering is performed in an improper manner. In this paper has been presented an analysis of the analog low-pass filtering impact on the useful signal parameters and noise signal parameters in the measurement channels. First, there has been analyzed an influence of this low-pass filtering using a 1st order RC filter with no load and with load at the filter output. Then there has been compared an operation of passive RC filters of the 1st, 2nd and 3rd order. Since the operational efficiency of the passive filters is often insufficient, there has been provided an example of the higher order active filters operation.

Influence of the intersegment scale on interaction of drive gear with a rack with an oval cross-section pins at the eicotrack haulage mechanism – FEM analysis

Abstract: The article presents a proposal for numerical analysis of the interaction of drive gear with a rack with an oval cross-section pins at the EICOTRACK haulage mechanism with two drive wheels (2BP) taking into account the influence of changes of the intersegment scale. The 2BP chainless haulage system was modeled in three-dimensional CAD environment by creating geometrical 3D models of the drive gear and rack pins. Due to the complicated meshing process and long FEA, resulting from the computational complexity, model of 2BP mechanism has been simplified. The aim of the FEM analysis, carried out in ANSYS Workbench, was to determine the values of intermesh force and directions of its impact during the feed for the simulated changes in pitch between the rack segments. The first part of the paper presents the EICOTRACK type chainless haulage system applied in longwall shearers, which is produced in Poland under the name 2BP. Then shown by the way of parameterization spatial 3D model of 2BP mechanism in ANSYS. It was conducted by the consecutive steps of modeling the interaction parameters relating to the drive gear with rack pins included the contact modeling, boundary conditions etc. Model discretization was made by sharing the continuum of solid model into finite elements. Forces acting on the drive gear was modeled. Tests were performed using a quasi-dynamic model by using the Finite Element Method. The results of FEM analysis are illustrated graphically in the form of characteristics a vertical component of intermesh force.

The architecture choice of the neural network used to describe changes in size of induced seismicity

Abstract: The article presents results of researches which have been done to define optimal architecture of neural network used to forecast changes in size of seismicity induced by mining works in progress. The set that had been used to learn neural network has included value of indicators that characterize changes of elastic strain energy (estimated with edge task translocation of spatial theory of elasticity given by H. Gil) and information about recorded level of seismicity, described by density of seismic events energy. While doing the research the influence of neurons number in the hidden layer of the network (from 1 to 16) was analyzed and neuron's characteristic (following activation functions have been considered: linear, logistic and hyperbolic tangent) for accuracy in describing induced seismicity changes when appropriately trained neural network is applied. Influence of neural network architecture on exactitude of change forecast of energy expenditure of rock mass shocks has also been checked. Calculation results for the region that is extremely at risk of shocks (region of mining works that are in progress in one of GZW coal mines) have confirmed possibility of using neural networks to estimate changes in size of induced seismicity connected with deposit exploitation. It has been also stated that forecast accuracy can be achieved by using not a very expanded neural network consisted of only two neurons in the hidden layer, however as an activation function it is favorably to use hyperbolic tangent.

Use of neural networks to calculate the velocity and acceleration of ground vibrations caused by mining tremors

Abstract: In many mines there is a problem with ground vibrations caused by severe tremors induced by carried out mining works. In the areas, where surface vibrations occurred due to highenergy tremors it is necessary to forecast the velocity and acceleration of vibrations that may occur during the future excavation process. This paper presents results of studies describing the possibility of using neural networks to forecast ground vibrations caused by mining tremors. During those studies data from highly seismically endangered region of Upper Silesian Coal Basin were used. The results of calculations proved the possibility of using neural networks to calculate the velocity and acceleration of ground vibrations caused by mining tremors. For the considered set of observations more precise results than, from widely used, a simple linear regression model, were obtained.

Using of the x-ray spectral microanalysis for the determination of elements associated with minerals of zinc-lead ores from the Klucze I deposit

Abstract: Elements associated with lead-zinc ores arouse a particular interest of scientists, especially that some of them are included to the group of critical elements. Now, in the European Union the obtaining a new sources of them is one of the priorities of the economy. Instrumental methods, which in the most accurate and reliable way, allow for determination of the concentration and occurrence forms of elements associated with sphalerite, galena and marcasite, should be used. One of such technique is X-ray spectral microanalysis, which was used in the researches of ore minerals from Klucze I deposit. In several micro areas of galena, sphalerite and marcasite, the qualitative and quantitative composition of elements was marked; on this basis, it has been found, that sulfides of zinc, lead and iron, beside cadmium Cd, arsenic As, thallium Tl and antimony Sb, contain elements included to the group of critical elements: tungsten W, dysprosium Dy, and iridium Ir. W, Dy and Ir were not previously described in the literature as associated elements of Zn-Pb minerals; in the studied minerals, these elements are dispersed mainly in sphalerite and marcasite. Their presence can be the premise regarding the possibility of obtaining alternative sources of critical elements.

They were measured on the segments of a measuring line established by “Budryk” hard coalmine. It was located perpendicularly to the runs of four longwalls. The values of curvatures were measured after the termination of an exploitation in one, two, three and four longwalls. The mean courses of curvatures were calculated via the difference of mean values of mining area inclinations (they were measured on the neighboring segments) divided by an average length of the neighboring segments which was measured during the subsequent observation cycles. Before that, were calculated the average values of inclinations via the difference of mean values of measured mining area subsidences divided by length of the segments which was measured during the subsequent observation cycles. The average values of observed subsidences were obtained by the use of smoothed spline functions. To compare the empirical data with their average courses, the values of standard deviations between the measured and mean values of curvatures (σK) and the variability indicators of curvatures’ random dispersion (MK) were calculated. Then it was made an appraisal of an effectiveness of reforecasting the values of mining area curvatures (by the use of the S. Knothe’s influences theory and the J. Białek’s formulas) with reference to the average courses of their measured values. There were calculated the values of deviations ΔK and dispersions MΔK of the used models.

Agreement between the theoretical and average courses of inclinations obtained from geodesic measurements carried out on observation line

Abstract: In this article was presented a comparison of the theoretical values of mining area inclinations with their average courses calculated from the results of geodesic measurements. The inclinations were calculated by the use of the S. Knothe’s theory and the J. Bialek’s formulas. The mean values of observed inclinations were obtained from the average values of measured subsidences. They were calculated on the way of an approximation by smooth spline. It was shown that in the case of inclinations, an error of the J. Bialek’s model is smaller than the S. Knothe’s model. The negative inclinations, they have been arised outside of an exploited longwall, are describing more precisely than the positive inclinations, they were arised above of an exploited longwall.

Restructuring of the global coal industry as a key driver for global competitiveness

Abstract: This paper presents an analysis of the deep and multi-faceted restructuring processes undertaken by Coal Mining Companies both in response to the 1973-1980 price shock on international oil and natural gas markets and to the increasing stringent sustainability and sustainable development criteria evident from the beginning of the 80’s of the XX century. In the introduction, the main goal of this restructuring on a mezzo and micro-economic level is presented being the maintenance or development of an international competitive position for a specific Industry Sector, Region or Company. A key aspect discussed in the paper are the developments introduced by coal mining companies in response to evolving demand levels or demand patterns emerging as a result of new technologies, new environmental requirements or different economic conditions. These include (among others): the growth of International Knowledge Transfer Processes for innovations and technologies used in coal extraction and enrichment processes; a “Pro-export” focus to planning and development projects for the exploitation of new reserves; development of Infrastructure for coal transportation from mining regions to export ports; implementation of International Cooperation models between Mining Companies, their major Customers and Coal Intermediaries which are based on platforms such as one developed by the World Coal Association. The conclusion presents the paper’s main finding that coal is maintaining its competitive position in the Global Economy as a Primary Energy Source and as an Industrial Raw Material primarily as a result of the restructuring which took place in the Global Coal Industry between 1980 and 2015.

An analysis of the influence of the single pre-existing crack on the state of stress and displacement in the vicinity of the circular horizontal opening

Abstract: An analysis has been conducted to address the fundamental question in rock and strata mechanics: how valid are the estimates obtained for the elastic stress distribution around a circular opening when the boundary of an opening is intersected by a plane of weakness? Five, the most frequently found orientations of the plane of weakness have been analyzed and it has been assumed that the discontinuity has zero value for tensile strength and cohesion, and is nondilatant in shear so it is a crack in nature. As a result it has been concluded that, in some cases, planes of weakness may have little or no effect on the boundary stresses. In cases where the boundary stresses are affected by the rock structure, the most important factors contributing to alteration of the elastic stresses have been found to be the orientation of the joint, joint shear strength and/or far field stress state in a rock mass.

Assessment of impact of physical properties of fly ash – water mixtures used for filling of shallow mine voids on the discontinuous ground deformation hazard

Abstract: Shallow underground voids represent potential source of discontinuous deformations, especially sinkholes, which it is possible to prevent through the filling of the voids with appropriately selected materials. In order to make the fall of rocks and backfilling of the void with loose overburden rocks impossible, material applied for the filling must be incompressible, waterproof, and fulfil other criteria required for mixtures intended to fill underground voids. In the article an assessment of impact of such properties as sedimentation, set and binding time, compressive strength, soak resistance and compressibility of chosen kinds of ash-water mixtures on the process of filling and stabilization of overlying rocks has been conducted, including the influence of the time on the change of the value of these parameters. Next the compressibility of ash-water mixtures and ashes in the dry and humid state have been compared. On this base an influence of a kind of fill material on the height of caving and fractured zones over a void has been determined, which position in relation to the hard rock roof and ground surface are essential for appearing of discontinuous ground deformation.

The use of electrical resistivity tomography for identification of shallow voids inside the rock mass

Abstract: The necessary condition for sinkhole creation on the surface there is a void occurrence inside the rock mass, located at shallow depths. Such voids may be of natural (eg. karst phenomena) or anthropogenic origin (as an effect of underground mining works). Whatever the nature of the void is, it creates a serious threat to the broadly understood public safety, due to the risk of discontinuous deformations. For this type of threat to be eliminated, it is necessary to precisely recognize the location of the void firstly, then its liquidation should be done, eg. by filling in with appropriate material. One of the non-destructive ways for determination of the shallow cavities location inside the rock mass are geophysical methods. In the paper, an example of using the electrical resistivity tomography for identification of shallow anthropogenic voids has been presented. The study concerns the mining area of one of the Upper Silesian Basin mines, where in the past the mining works were carried out at shallow depth. This area was chosen because of the relatively well-recognized geological and mining situation, but above all for the sake of macroscopically visible changes in the terrain morphology, corresponding to the location of the mine workings identified on the basis of mining maps and the sinkhole created in the past in this area.

The using CFD to determine the impact of ventilation systems on the location a zone particularly endangered by endogenous fires in longwall goaf

Abstract: In underground coal-mining during ventilating of operating longwalls takes place migration of parts of airflow to rockfall goaves. In a case when in these goaves a coal susceptible to self-ignition occurs, then the airflow through these goaves may influence on formation of favorable conditions for coal oxidation and subsequently to its self-heating and self-ignition. Endogenous fire formed in such conditions can pose a serious hazards for the crew and for continuity of operation of mining plant. In the paper results of numerical analysis of airflow through rockfall goaves ventilated in “U-type” from boundaries system and „Y-type” are presented. The aim of the analysis was to determine in these goaves a zone particularly endangered by endogenous fıres. For determined mining-geological conditions, the critical value of velocity of airflow and oxygen concentration in goaves, conditioning initiation of coal oxidation process were determined.

Designing the course of exploratory boreholes for drainages of the underground water reservoir on the example of selected coal mine

Abstract: Underground water reservoirs are source of possible water hazards for safe digging of mining excavations, located within immediate vicinity. In order to eliminate existing water hazards, exploratory boreholes drainages of water reservoirs are performed. The effective designing of the course of exploratory boreholes is particularly important, in order to efficiently drain underground water reservoirs, to lower the water table to the level that ensures safe digging of the mining excavations. The paper presents designing of the course of exploratory boreholes, which drain underground water reservoir. For this study the underground water reservoir, located in old workings of the selected coal mine of the Upper Silesian Coal Basin (USCB), was chosen. In result of the map’s analyses, the courses of the boreholes were designed. Moreover, the drilling parameters for the planned drainage of the water reservoir were determined. The design of boreholes presented in the article allows for safe digging of the mining excavations, located significantly close to the underground water reservoir. The boreholes were designed with the use of AutoCAD program. Designed boreholes were presented in the form of sketches.

Numerical model of CO2 emissions from a closed shaft

Abstract: The results of numerical simulations into carbon dioxide emissions from a closed shaft are presented in the article. FDS programme including Pyrosim mode was applied to computing. The programme belongs CFD (Computational Fluid Dynamics) group which are designed for simulations of fluid flow. Validation was based on experimental data obtained during „insitu” measurements above closed Gliwice II shaft. The concentration of CO2 in assumed mixture was 3,24%vol. (maximal detected value) and two wind variants were set up. The first was for wind velocity 1,0m/s from the south (according to measurements conditions). The second variant was for wind velocity 0,0m/s. Then the results were compared. Comparing the variants, the difference in gas stream distribution in vicinity of the shaft was observed. In contrary to assumed wind velocity as 1,0m/s, under „no wind” conditions gas flowing out of the shaft can create local hazardous accumulation. It is crucial when safety procedures for post – mining areas are elaborated. Created model can be easily modified and applied in the future for many aspects of possible gas flow from an underground to the surface, eg. during mine closure, CCS (Carbon Capture Storage) or UCG (Underground Coal Gasification).

Application of MERIT survey in the assessment process of the management quality of the occupational health safety – case study

Abstract: The experience of economically developed countries proves that the quality of actions undertaken in the realm involving the management of the occupational health and safety may substantially contribute the attainment of higher OHS standards. A significant role in the improvement of OHS management quality is played among others by audit surveys of the management system of OHS which is viewed as a form of controlling tool. One of the first solutions of that type was applied in the mining industry in Poland, and they were based on the MERIT survey (Management Evaluation Regarding Itemized Tendencies). The mathematical model applied within the scope of that survey makes it possible to determine assessment indexes (final index WZBP and partial indexes WOPi). The results obtained from the survey carried out on a group of respondents – employees of departments of mining coal – were then used for the prediction of the assessment of the quality of actions undertaken in the area of OHS management (the linear discriminant function was applied as the prediction method).

Dynamic model of a kaolin deposit

Abstract: This paper focuses on research within the project TE02000029 Competence Centre for Effective and Ecological Mining of Mineral Resources, granted by The Technology Agency of the Czech Republic, and, more specifically, on the research within its work package WP4 – Spatial modelling of mineral deposits. The focus of this work package is digital modelling of selected nonenergetic raw materials, which belong to the critical commodities, as defined by the European Union. For modelling these deposits, suitable mathematical procedures, based on study and reevaluation of archived data, are needed. One of the selected deposits is a kaolin deposit near the village Jimlíkov near the city Karlovy Vary. In this paper, we show a step-by-step procedure for creation, visualization and evaluation of a 3D model of the deposit. This methodology, along with our recently developed software allows a user to create a variant of this dynamic model for the same or similar types of deposits, enables rapid updating of these models when adding or changing the input data on the basis of new mining exploration or when changing modelling parameters such as using multiple variations interpolation parameters. Our methodology leads to a more advanced deposit evaluation, including adaptive estimates of the reserves based on the usability requirements we choose. In January 2017 our software was tried out in the company Sedlecký kaolin a. s. in Božičany and our dynamic model is fully applied in practice.

The focus of this work package is digital modelling of selected nonenergetic raw materials, which belong to the critical commodities, as defined by the European Union. For modelling these deposits, suitable mathematical procedures, based on study and reevaluation of archived data, are needed. One of the selected deposits is a kaolin deposit near the village Jimlíkov near the city Karlovy Vary. The article describes the implementation of the methodology used for processing deposits of kaolin in Visual Studio 2015 by means of objects of Surfer and Voxler created by Golden Software. This software solution is installed at the company Sedlecky kaolin a.s. and thus is fully exploited in practice.

The determination of the mineral percentages in granite

Abstract: Recently a new method (CQMA) for the quantitative determination of minerals in solid samples has been suggested and verified on 6 standards of rocks samples. This method is based on the recalculation of the elemental bulk chemical analysis on the quantitative contents of the mineral phases identified in sample. This method is based on the optimization procedure and except elemental bulk chemical analysis requires the identification of minerals and finding their crystallochemical formulas. The mineral phases as well as chemical analysis are determined by usual analytical methods. In this contribution the results of quantitative calculated minerals by Chemical Quantitative Mineral Analysis (CQMA) are compared with the reference analysis of granite. Mineral analysis of granite was performed by optical and XRD methods, chemical analyses by classical and XRF methods and crystallochemical formulas of minerals were identified by Rietveld technique.

Statistical evaluation of the efficiency of the two types of protection systems in carotid artery stenting

Abstract: The article deals with the evaluation of the efficiency of the two types of protection systems in carotid artery stenting (CAS). Carotid artery stenting is a treatment of carotid artery stenosis, which is a narrowing of the carotid artery caused by a plaque buildup in the artery wall. Pieces of plaque can break off and block the blood flow in the artery, which leads to a stroke. Carotid artery stenting is an endovascular surgery where a stent is deployed within the lumen of the affected carotid artery to dilate it and prevent a stroke. Two types of embolic protection devices are commonly used during CAS - distal protection devices (filters) and proximal protection devices. The aim of this study was to determine whether the two protection systems differ in the number and in the location of new ischemic lesions after surgery. Statistical analysis was carried out with the programs SPSS and Microsoft Excel. Mann-Whitney test, χ2 test and Arcsine test were used and the value of p = 0.05 was taken as a level of significance.

On homogeneous functions in second-order field theory

Abstract: The classical concept of a homogeneous function is introduced and extended within the theory of differential groups, known in the theory of differential invariants. Invariance under reparametrizations of solutions of partial differential equations is studied. On this basis the wellknown generalizations of the Euler theorem are obtained (the Zermelo conditions). The positive homogeneity concept is then applied to second-order variational equations in field theory.

Note on circulant matrices of degree 9

Abstract: Circulant matrices provide quite a wide range of applications in many different branches of mathematics, such as data and time-series analysis, signal processing or Fourier transformation. Huge number of results concerning circulant matrices could be found in algebraic number theory. This is because we could construct factor ring isomorphic to the p-th cyclotomic field Q(Ƈp) from the ring of circulant matrices degree p, where p is a prime. In this paper the connection between ring of circulant matrices of degree 9, C9, and the cyclotomic field Q(Ƈ9) is shown.

Modern Taylor Series method in numerical integration: part I

Abstract: The paper deals with extremely exact, stable, and fast numerical solutions of systems of differential equations. It also involves solutions of problems that can be reduced to solving a system of differential equations. The approach is based on an original mathematical method, which uses the Taylor series method for solving differential equations in a non-traditional way. Even though this method is not much preferred in the literature, experimental calculations have verified that the accuracy and stability of the Taylor series method exceed the currently used algorithms for numerically solving differential equations. The Modern Taylor Series Method (MTSM) is based on a recurrent calculation of the Taylor series terms for each time interval. Thus, the complicated calculation of higher order derivatives (much criticised in the literature) need not be performed but rather the value of each Taylor series term is numerically calculated. An important part of the method is an automatic integration order setting, i.e. using as many Taylor series terms as the defined accuracy requires. The aim of our research is to propose the extremely exact, stable, and fast numerical solver for modelling technical initial value problems that offers wide applications in many engineering areas including modelling of electrical circuits, mechanics of rigid bodies, control loop feedback (controllers), etc.

Symmetrized semi-smooth newton method for solving 3D contact problems

Abstract: The semi-smooth Newton method for solving discretized contact problems with Tresca friction in three space dimensions is analyzed. The slanting function is approximated to get symmetric inner linear systems. The primal-dual algorithm is transformed into the dual one so that the conjugate gradient method can be used. The R-linear convergence rate is proved for an inexact globally convergent variant of the method. Numerical experiments conclude the paper. The contact problems are important in many practical applications, e.g., biological processes, design of machines, transportation systems, metal forming, or medicine (bone replacements).

Damped solutions of singular ivps with ø-Laplacian

Abstract: We study analytical properties of a singular nonlinear ordinary differential equation with a ø-Laplacian. We investigate solutions of the initial value problem (p(t)ø(u’(t)))’ + p(t)f(ø(u(t))) = 0, u(0) = u0 ≡ [L0,L], u’(0) = 0 on the half-line [0,∞). Here, f is a continuous function with three zeros, function p is positive on (0, ∞) and p(0) = 0. The integral ʃds ds./p(s) may be divergent which yields the time singularity at t = 0. Our equation generalizes equations which appear in hydrodynamics or in the nonlinear field theory.

Uniform horizontal projectile motion

Abstract: In the paper we present the modification of the classical horizontal projectile motion in the homogeneous gravitational field called uniform horizontal projectile motion. The particle passing in the homogeneous gravitational field is treated as a mechanical system subjected to a nonholonomic nonlinear constraint which keeps the magnitude of the instantaneous velocity of the particle constant during the motion. We present the comparison of the kinematic parameters of both motions (classical and uniform horizontal projectile motions) under the same initial conditions. The presented problem can serve as a suitable topic for an elementary course of theoretical mechanics on the university level.

Green tensor in material sciences

Abstract: Material properties of heterogeneous nanomaterials modelled by effective medium approximation (EMA) demand specific approaches when metallic inclusions in a host medium are exposed to external magnetic field. Resulting induced anisotropy of permittivity is manifested itself by a specific form of polarizability tensor. In presented work, this one is applied in the so called “strong-couple-dipole” (SCD) method, where the electromagnetic Green tensor is of key importance. The results are oriented to the magneto-plasmonic sensor element design for the use in biology or chemistry.

Economic and ecological costs of heating and optimum thickness of the thermal insulation

Abstract: This article presents the method of the assessment of the ecological costs of heating, which was modelled after the method for assessment of the economical costs of heating. Thanks to that, it is possible to analytically describe, in a similar fashion to the economic one, the ecological net present value of the thermal insulation investment, and to assess the optimum thickness of the thermal insulation both from the economic and ecological perspective. Different cases occurring in Polish conditions were also examined. Different variants were also analyzed: construction material of the building wall, type of a heat source, type of the thermal insulation material. The diversity of the climate zones in Poland was also taken into consideration. For all examined variants, the assessed optimal thickness of the thermal insulation layer from the ecological perspective was much bigger than from the economic perspective. Implementation of the greater thicknesses of the thermal insulation than the optimal from the economic perspective is beneficial. In this way, with the small decrease of the economical benefits, the greater ecological benefits from the thermal insulation investment are achieved.

Analysis of the share and importance of quality control methods used to detect non-conformance of aluminum profiles

Abstract: This paper presents the results of the analysis of the contribution and importance of specific quality control methods used to detect the non-conformance of the aluminum profiles produced by the pressing process. Specific quality control methods such as measurement, testing, verification, visual inspection, numerical control and alternative control have been analyzed. The quality control processes used were identified. The Pareto-Lorenz diagram was used to identify the critical non-conformity of the examined product over a period of one year. The relationship between the presence of quality control methods in detecting nonconformities and the inconsistencies detected by the quality control methods examined has been analyzed. An analysis of the risks associated with nonconformities detected by the tested quality control methods was also conducted based on the FMEA indicators (priority numbers). The control method that most often involved detecting non-conformance of aluminum profiles and detecting the most incompatibilities is the visual inspection. This control is also responsible for detecting inconsistencies with the greatest risk and importance for the customer, and hence the need for managers to increase their effectiveness.

The use of CFD for assessment methane hazard

Abstract: One of the commonly present gas hazard in hard coal mines methane hazard. The most endangered region by this hazard, during ventilation of longwall in „U from boundaries” system is the crossing with ventilation roadway (so called “upper corner of longwall”). Accumulation of methane in this place results from its release from goaf. Therefore, in order to decrease methane concentration in this region, auxiliary ventilation devices are used. In the paper results of numerical studies of distribution of methane concentration in hazardous zone (upper corner of longwall) are presented. The obtained results clearly show that numerical methods, combined with the results of tests in real conditions can be successfully used for the analysis of variants of processes related to ventilation of underground mining, and also in the analysis of emergency states.

Safety management in food production to improve the product quality

Abstract: In this paper the new idea of safety management in food production is presented. Legal regulations on food production and food trade including legal regulation imposing the obligation to implement are described. The obligatory and non-obligatory food health safety and food quality management systems in the food industry are presented. Also the new idea based on the principles of risk analysis implementation and description of risk analysis elements such as risk assessment, risk management and risk communication, and connections between them. Article provides explanation of all important terms connected with risk analysis. Food safety management is to not only take care of the quality of the product in industry, but also ensure the maintenance of product safety at the time of consumption. In order to protect the health of the consumer in the world are increasingly set up Appropriate Level of Protection (ALOP) (expressed for instance as a numbers of illnesses in a population per year). The current Risk Analysis, it is proposed that, when deemed appropriate, competent authorities can formulate a so-called Food Safety Objective (FSO). FSOs and POs (Performance Objective) are new concepts that have been introduced to further assist government and industry in communicating and complying with public health goals. A prominent part of the risk analysis is microbiological risk assessment (MRA), the process of assessing and characterising the risk posed by a hazard in a food within a certain population. The risk analysis as a new ways for food safety have been developed. Risk assessment of microbiological hazards in foods is now a well-recognised and accepted approach within food safety risk management. In the future, according to circumstances and availability of data, the coexistence of qualitative and quantitative risk assessment is expected as well as the one of hazard and risk focused approaches to risk management.

Stocktaking of innovative energy waste recyckling technologies

Abstract: The purpose of this article is an inventory of innovative technologies for the recovery of energy waste – waste from the processes of combustion of fuels and technologies used for flue gas desulphurisation in power plants and/or electrical power and heating plants. A large amount of waste is still deposited in landfills or stored (annually even 40% approx.), which exposes them to loss their properties and thus – limits their possible future development in the industry. Industries such as mining, construction and road construction have used the raw material potential of energy waste for many years. However, with the advancement of technology, more innovative forms and possibilities of using energy waste arise, and finding new and newer directions of their development becomes necessary. Thanks to new technologies used in the fuel combustion process (enforced by legal regulations and environmental exacerbations), the generated waste will gain new properties. This will allow them to be better developed in such industries as agriculture, nanomaterials or environmental protection, where the share of all generated energy waste has so far been only about 10%, and used in other industries.

Domagnetic markers could be useful for pre-operation demethanization of hard coal deposits – selected conclusions from studies on gas-bearing shales 

Abstract: The paper discusses the possibilities of using magnetic markers for pre-operation demethanization of hard coal deposits based on the knowledge and experience of the authors, related to fabrication of magnetic markers for shale gas exploitation by means of hydraulic fracturing and literature review. Magnetic materials may be added to the fracturing fluid, as the magnetic marker allowing to better determine the range and efficiency of hydraulic fracturing. The application of appropriate magnetic markers can significantly improve the efficiency of coal-bed methane gas extraction. Thus, effective coal-bed methane fracturing should also signif-icantly reduce the methane hazard occurring during hard coal mining. Selected properties of potential magnetic materials for pre-operation demethanization of hard coal deposits were discussed in the work. Potential proppants for hard coal deposits fracturing can be character-ized by much smaller requirements in comparison to proppants used for shale gas extraction which, as a consequence, may result in much higher cost-effectiveness of their use and have a decisive influence on the choice of their production technology. However, these issues require further detailed research.

Study the relationship between the average remuneration and production and productivity in hard coal mining in Poland
Abstract: The correct structure of remuneration that includes, among others, performance bonuses may be one of the key elements needed to improve productivity in mining companies. Well-structured remuneration aims to stimulate more efficient work and development of em-ployees. This goal can be achieved when the structure or level of remuneration prompts desired behaviors in terms of work performance, which will impact work outcomes and overall business productivity. However, when analyzing the structure of average remuneration of manual wor-kers employed underground in randomly selected mining companies in Silesia, no effective structures were reported. Accordingly, this publication presents the results obtained when stu-dying the correlations between the average remuneration and production and work productivi-ty in hard coal mining in Poland, looking for the relationship between these elements of the production process.

Abstract: The underground exploitation of thin seams, ie. seams with the thickness of up to 1.6 m, is associated with a numerous limitations and difficulties, therefore they are usually exploited only after selecting deposits that are more economically viable, ie. medium and thick ones, or when it is required for the safety reasons. However, the depletion of hard coal deposits argues in favour of their exploitation. The wide variety of conditions has led to the development of many methods and systems of exploitation. The article focuses on longwall systems of exploitation of these seams. The most important assumptions and advantages of wall exploitation were presen-ted and the mining machines used as a crucial element of the mechanization systems were di-scussed. Attention was also paid to the solutions of shearers and coal plows not used in Poland. Finally, an innovative solution of a longwall system equipped with a single-cutting head lon-gwall shearer working in walls from 1.0 to 1.6 m was briefly presented.

Description of the surface vibrations caused by rockmass tremors taking into account the directivity of vibrations’ attenuation
Abstract: Seismicity induced by conducted mining works in many cases causes the strongly felt surface vibrations. In order to record ground vibrations occurring in the mining areas, network of observation stations is being expanded. Data from these point observations are used to repro-duce acceleration (velocities) fields of ground vibrations over the entire area affected by dynam-ic impacts of rockmass tremors. Many times, commonly used attenuation relations do not allow to obtain a sufficiently practicable accuracy of the description of the results of observations. In such cases, using the attenuation relationship that takes into account the directivity of the propagation of vibrations may allow to increase the accuracy of the reproduction of ground vibration accelerations (velocities). In the article, the reproduction’s results of recorded acceler-ations of ground vibration caused by rockmass tremors, occurring in the area of one of the GZW mines, are presented. In all cases, the directivity of vibration propagation was observed. The results of the calculations show that the direction of lower surface vibration attenuation is par-allel to the direction of the tectonic fault adjacent to the epicenter of the tremor generating these vibrations.

The technical possi-bilities of producing and supplying inert gas should be taken into account. It has been suggested, determine the distribution of oxygen concentration in the goaf of longwall before and after iner-tization, as well as determine the distribution of airflow in the goaf may be helpful during the process of designing. The range of oxygen concentration distribution and velocity distribution of the air flow in the goaf of longwall, which may favor the process of self-heating of coal, are giv-en. This area should be inertisated. Guidelines for inertisation of longwall goaf have been devel-oped. It was noted that the planning of the operation should be a multi-stage process, the steps listed and their sequence indicated. An algorithm for the inertisation of the longwall goaf was also presented. In summary, it was pointed out that the criteria for assessing the effectiveness of inertisation could be helpful in deciding on the choice of this method of prevention.

Comparison of periodic trainings on ohs carried out in active mining and wished installations
Abstract: In the article the author discusses the problem related to the implementation of peri-odic training among underground workers. Trainings are usually carried out en masse and there is no division into active and liquidated mines. The publication asked about opinions on periodic training of employees of active mining plants and liquidated in the form of a short anonymous survey. To improve the course of periodic training, modifications to the framework training programs should be introduced. The modification will allow for the inclusion of irregu-larities and will specify and detail the issues implemented directly in active and liquid mining plants. In addition, a survey was conducted among employees taking part in training. The ques-tionnaire consisted of fourteen questions concerning, among other things, the scope of the train-ing conducted, including employees working in liquidated mining plants as well as observations of persons trained in this field.

Influence of the emission of methane disposed from ventilation shafts of hard coal mines on the state of atmospheric air
Abstract: Methane CH4 is a gas that is primarily produced by the anaerobic decomposition of organic matter in biological systems as well as from anthropogenic sources. In 2014, methane emissions were 41.33 million tonnes of CO2 equivalent and 46.1% less than the baseline year. At the same time, methane, like CO2, has been recognized by the International Panel on Climate Change as a greenhouse gas, a substance that absorbs infrared radiation, and thus contributes to global warming. According to the IPCC, methane concentration in the atmosphere has in-creased by approximately 162% over the past 250 years, and now half of its current stream emitted into the atmosphere comes from anthropogenic sources, the ones most affected by hu-man activity. One of the main sources of methane release into the atmosphere is mining. Poland, along with China, the United States, Ukraine, Russia and Australia, accounts for about 2.7% of the world's largest methane emitters in the coal mining sector, which accounts for around 8% of global anthropogenic methane production in 2010. Mining managers are obliged to capture methane in order to ensure safe working conditions for mining crews. The captured methane can be disposed of or released into the atmosphere (VAM). However, taking into account many sources of methane emissions, estimating its amount from individual sources is burdened with very high uncertainty, which in turn hampers accurate forecasting of climate change. In order to accurately predict climate change and help to enforce policy conventions for avoiding green-house gas emissions, adequate knowledge of the sources and absorption of greenhouse gases is needed. Due to the importance of the issue, our current understanding of the sources and pro-cesses accompanying the leakage of methane into the atmosphere is still insufficient. The pur-pose of this article is to determine the reasons for methane release from hard coal seams, as well as to illustrate the release from ventilation shafts on the example of a mine consisting of three works.

Numerical simulation of methane outflow into roadway
Abstract: This paper presents the results of numerical modeling of methane outflow into road-way depending on the location of the methane-bearing layer in relation to this roadway. The assessment of changes in the roadway area was made using the anisotropic ubiquitous joint model. The process of gas flow through porous medium was simulated based on the single-phase Darcy flow condition. For numerical modelin, the FLAC finite difference program was used. De-termination of the methan flow in the rock mass was coupled with calculations of changes in stress and deformation of the modeled medium. Presented results of computer simulated me-thane outflow into roadway should be assessed as qualitative. These results show the capabili-ties of used FLAC program. Use of two-dimensional rock mass model is a very big simplification, which enables assessment of methane outlets in the excavated raodway (excluding the face zone of the excavated roadway).

Experimental research of the location of links on the chain drum with a high degree of wear  

In order to meet the requirements of modern coal mining, scraper conveyors with increasingly higher drive powers, higher speeds of scraper chains, larger masses and sizes of link chains and scrapers are constructed. Entering the chain links in engagement with the drum teeth segments and disengaging the links in the slip of the links on the tooth flank is accompanied by significant pressure and friction forces having a decisive impact on the wear of the tooth segments and the bottoms of the drum seats. The wear of the chain drum components and the extension of the chain pitch change the geometrical relations that determine the location of the links in the drum seats. In the tested conveyor equipped with a scraping chain and a chain drum withdraw from operation due to a high degree of wear, quick change of the position of the chain links during their running on the drum was registered by speed cameras. Registration and analysis of the chain-to-drum connection process confirmed the occurrence of slip of all horizontal links coming into engagement with the flanks of the teeth towards the bottoms of the drum seats.

Chosen technical aspects of shaft deepening process 

Abstract: Due to a necessity of exploitation of seam laying at greater depths there is a need of resolving a problem of gaining access to those deposits. Limiting of investments in the industry has led many of the mines to conduct sublevel mining. However, it seems reasonable to consider a possibility of a traditional solution to this problem, which is sinking new shafts or deepening existing ones. All of the presented solutions have their pros and cons. The article presents chosen technical aspects of sinking and deepening mine shafts. It was assumed, that this solution is in many cases much more profitable than sublevel exploitation. Currently employed methods of shaft deepening, along with coal shearing and transport systems, shaft reinforcement and safety of this process were discussed. Aim of the presented work is to reason that in current state of technology sinking new shafts and deepening existing ones makes sense economically and technically.

The concept of eco-management of waste electrical and electronic equipment in the rural areas 

Abstract: Waste electrical and electronic equipment is a significant problem in waste management. Inparticular, it can be observed in small towns and rural areas. When it comes to the rest of waste which is a part of municipal solid waste, the problem has been (to a certain degree) resolved, but in terms of electrical and electronic waste, it requires a thorough analysis and undertaking actions in order to find a solution. The municipality is responsible for removing pollution from its area, therefore the municipality must be accurately informed of places and ways of removing electrical and electronic waste by its inhabitants. In practice, however, the users of electrical and electronic equipment are obliged to return wasted equipment to an applicable collection point. The problem of waste electrical and electronic equipment with the special attention paid to the Polish and European legislation in this regard, was discussed in the article. The present state of management of waste electrical and electronic equipment in the rural areas was discussed, as well as remedies on that point were presented. Also, the concept of system of management of waste electrical and electronic equipment in the rural areas, considering the investment strategy in WEEE collection points, were presented. The material presented in the article should encourage the discussion on subject of management of waste electrical and electronic equipment and possibilities of enhancing the present condition of the environment.

”The second life” – how does form determine functions  

Abstract: Using the natural skills of interpretation and reinterpretation, we are able to give "the second life" to items, architectural objects and phenomena. When creating it, we do not always have to design new forms that have never been known to anyone. Definitions, names, functions can be only a starting point for the further creation process. This way of thinking teaches and develops – humility and imagination. Our article is an attempt to answer several questions related to the above train of thought: Is the once given definition, the only proper one ? Is it worth trying to ”look at something differently” ? What are the consequences of creating ”the second life” ? What is the role of beauty and how to care for it ? And finally – where art and technology are connecting in this process. Can the technique be perceived as an art itself ? Our thoughts have been illustrated with several examples from various fields of artistic activity. The review of the works will allow to find answers not unequivocal, but the ones giving an opportunity for individual thoughts and conclusions about the relationship between art and technology.

Early baroque art in the language of contemporary technology – comparative analysis: Villa Giulia versus the student design  

Abstract: The paper seeks to answer the question about the relationship between art and modern technology. The main assumption is to investigate the influence of technological advancements on artistic expression. A clear designer’s vision realized without contemporary construction solutions is exemplified by Villa Giulia, an early Baroque residence by G. B. da Vignola. The student design, ‘A Country House’, represents a single-family home based on modern solutions. The buildings enable comparing their features while differentiating two categories. The first category follows the contrast design principle of element arrangement and functional zoning. The latter focuses on the specific arrangement of elements and its impression effect. This includes the concept of depth and the modest exterior hiding a rich interior. The research method consists in the simplification of projections and cross-sections of these houses. Thus, it is possible to indicate distinct common features and apparent conceptual analogy between Vignola’s intent and the student vision. The conclusion is that art is meant to formulate an objective and technology should make it real in a genuine dimension. It may be observed that contemporary solutions enhance universality and adjustment of the idea of the master of Baroque architecture to the realities of the 21century man.

A new dimension of ceramics. Digital tools in the processes of shaping ceramics items – 3D printing  

Abstract: Ceramics has always played an important role in human life. In the last several dozen years it has become an excellent material raising the value of raw materials and materials used in distant industries. Aside from a numerous group of ceramic materials used in artistic ceramics, newer materials appear, with improved strength parameters, used in engineering ceramics. The information about the use of ceramic coatings in turbine engines or worn textile products is no longer surprising. Such a large expansion of ceramics would not have been possible if modern, innovative technologies had not appeared. The essence of progress is the change in thinking about creation and its application. Contemporary researchers, scientists, artists, and designers focus on these problems. Undoubtedly, in the near future, the digital language will almost completely supplant the analogue transmission. And the awareness of the imminent arrival of something new should be an argument that convinces contemporary artists to gradually introduce themselves in advanced technology.

Technological progress has certainly influenced the evolution of our behavior. It makes life easier, it inspires us, but at the same time, it evokes a sense of technology dominance. Already in the nineteenth century, the American poet and philosopher Henry David Thoreau stated: "Man has become the tool of his tools." Thoreau draws our attention to the question of submission, dependence in the context of what man created. Is man always able to control the object ? Can an object dominate a person? This seemingly naive question touches the issue of fascination with the subject in the context of its value, context, usefulness or type of technology used. In the ancient beliefs of indigenous tribal cultures, especially before the development of organized religious systems, all non-human beings possessed a soul including objects. Objects, parts of machines and devices often become modern totems, to which worship is given. Surrounded by an irrational cult, they become modern fetishes endowed with magical power whose source is mysterious or not fully understood. In the text, i undertake issues from the borderline between art and technology, where nuances, dependencies and mutual relations between them are most visible. Moments in which a specific energy exchange takes place between the subject and the user, between the object and the observer. This relationship has also become important in many of my projects, whether through a specific object or activity but also technique and method of implementation. In the second part, I present selected realizations of contemporaryartists: designers or artists in which the technological context as well as the relationship with the subject, determine the direction of their actions or inspiration.

Landscape of communities. Ants in the service of beauty  

Abstract: In 2012, the artist Elvin Flamingo realized a project entitled "The Symbiosity of Creation", which was designed for at least twenty years of existence. Its basis is ants, which in this project abolish the classic dichotomy of Nature-Culture, and at the same time they deny the classical division between the creator and his work. The co-occurrence created by the artist with ants and technology determines not only posthumanistic perspective in art, but also contributes to increasing attention to technology, technology and animal design – the human world.

Hidden but incredible – road tunnels  

Abstract: Tunnels are the objects which in general have only practical features. As far as other objects made by engineers such as viaducts or buildings aside from functional properties have aesthetic values too, the tunnels are located at the opposite end. What is more, it can be revealed that every tunnel is somewhat in contrary to the concept of object: it is just a hole, an empty space under the Earth surface. However, despite such extremely usable characteristic some more abstract ideas can be associated to the tunnels. The paper discusses the importance of tunnels for modern society, some historical facts are mentioned and the most severe dangers connected with tunnels usage are pointed out.

Characteristics of ion nitriding with the active screen of non-nitriding metallic materials  

Abstract: In the article for a selected group of non-nitrite materials (austenitic steels: X5CrNi18-10, X2CrNiMo17-12-2, technical titanium Ti99.2, titanium alloy Ti6Al4V), the properties of the surface layers (nitrogen diffusion depth, hardness, abrasiveness) obtained as a result of the nitriding process were compared an ionic sample placed directly on the cathode and a sample placed on the cathode using the active screen. The obtained results clearly indicate that in this case the "active screen" method is more effective. The attractiveness of this innovative method can be additionally demonstrated by the fact that implementing it to industrial conditions is a simple almost cost-free operation (costs associated with the creation of an active screen).

Teletransmission intrinsically safe barriers as an element of safety in wired telecommunication systems


Abstract: In methane coal mines, communication and alarm systems must be intrinsically safe, adapted to work at any methane concentration. Intrinsic safety of telephones and alarm sirens is provided by special teletransmission devices connected to each telecommunication line, colloquially called intrinsically safe barriers. For several dozen years, in all technical solutions of intrinsically safe barriers, the separation of the underground circuits from the surface installations is provided by the transformer. In the HETMAN communication and alarm system, currently used in several mines, capacitors were used for the first time as the separation elements in the line circuit of the intrinsically safe teletransmission barrier. The article discusses these two basic technical solutions of the intrinsically safe teletransmission barriers used in telephone communication and in the alarm systems. The basic functions of an intrinsically safe barrier in the voice communication system in underground mines also have been presented.

Quality assessment of conical picks for public procurement purposes


Abstract: The article presents the results of a study on the quality of conical picks for the purposes of tender procedures in accordance with the public procurement law in Poland. The pick studies presented here are one of the few that in practice allow the selection of an offer based on objectively determined numerical indicators defining the quality of the product and not only on the basis of price. Thanks to this, the contracting party can decide the relevance of price and quality in their evaluation of a pick. The geometrical and material parameters required in a tender, if not met, are the basis for rejecting a given offer of picks. The numerical parameter influencing the final evaluation of the offer is the picks' rate of wear. The article presents the results of studies on geometric parameters, material parameters and the rate of wear of 48 sets of picks conducted for a tender consisting of 14 tasks. The tender was conducted for 6 underground mines of a coal company. Five producers submitted their offers for selected tasks in the tender.

The impact of geometric data generalization on the accuracy of deformation predictions of the mining area – construction of a digital deposit model


Abstract: The article presents the problems related to the construction of a digital model of the deposit, which may be the basis for the preparation of exploitation data for the purpose of prognostic calculations. DDM (Digital Deposit Model) is understood here as a database along with software allowing at any point for determining elevation points, thickness, roof lowering, etc. Seam floor is represented as a network of triangles TIN (Triangulated Irregular Network) with vertices located on borehole points, elevation datapoints and faults. In the same way, we create a TIN surface of coal and rock thickness, density, sulphate, anticipated floor dinting, etc. The program allows for visualization of the surfaces by means of isolines and coloring. It is possible to generate a cross-section through a rock mass between any points, which is an excellent verification tool of the model. Projecting of any objects to the surface of calculated lowering allows for easy preparation of the forecasted elevation map. We can also edit surfaces: adding points, gradating propagated changes, extrapolating, smoothing and simplifying. The article analyzes the creation and editing of exploitation parcels based on the digital deposit model. The method of bilateral communication between a digital map and mining area deformation forecast software. The possibilities of the Geolisp program in the scope of visualization of the results of prognostic calculations, searching for facilities meeting specific criteria, generating reports, coloring buildings according to the deformations category etc. were listed.

Methane hazard – literature review


Abstract: One of the most dangerous phenomena associated with the extraction of hard coal is the occurrence of methane in its seams. Despite enormous progress in identifying and combating the methane hazard, its growth is observed in many mining areas of mines, which is strongly related to the increase in the depth of exploitation, the increasingly methane-free nature of deposits and the gas reservoir pressure. For the purpose of effectively counteracting dangerous phenomena related to methane hazard, aimed at improving occupational safety and health in mining, it is indispensable to cooperate with all mining industry, in particular with scientists and R & D units. This article analyzes the available literature in this area and presents the development of methods and means for the diagnosis and forecasting of methane hazard.

Abstract: Determination of the measurement procedure statistical burden makes it possible to determine the rate and type of systematic errors, which can be eliminated by proper amendments. The best method to estimate this parameter is to use linear regression. The publication of the new standard no 17025 for testing and calibration laboratories imposes on the above-mentioned units a change of approach in some works’ aspects. The changes that were made refer as well the measurement consistency maintaining area. In this case, determination of the statistical burden must be carried out by using the certified data of comparison from reliable manufacturer. The maintenance of the measurement consistency indicates that the linear regression determined for the estimation has to be weighted illative to ( X and Y) type.


Key words: statistical burden, standard no 17025, linear regression, certified data of comparison

General overview of the mechanical coal processing plants in PGG S.A.


Abstract: In Poland, Grupa Górnicza S.A. has 8 coal mines and one eco coal production plant. As part of the mines, there are 13 Mechanical Coal Processing Plants connected technologically with the mining process. The processing plants have diversified coal enrichment technology depending on the type of coal processed. Two types of coal are produced depending on the application: steam coal and coking coal. At the moment, coking coal is produced in two mines: KWK ROW and KWK Ruda. Steam coal is produced in other mines. Two types of eco coal are currently produced at ZPE WOLA. The eco coal is also produced at KWK ROW Ruch Chwałowice and at KWK Wujek. In KWK Wujek, certified aggregate is also produced based on the collected post-wash stone. The offer includes road aggregates in accordance with the applicable standards. The coal produced by PGG S.A. is characterized by low sulphation.

The process of coal enrichment in processing plants is mainly carried out based on three methods of enrichment:

  • gravity in heavy suspension liquids,
  • gravitational in an aquatic center,
  • flotation.

In all processing plants, coal with coarse and medium grains is enriched.

Production of ecological coal in the aspect of air protection


Abstract: The main components of the air are nitrogen, oxygen and argon totaling 99.9% by volume. The remaining ones with the highest share are carbon dioxide, neon and helium. In addition to solid components, atmospheric air contains a number of other components that are emitted to the atmosphere as a result of processes occurring in nature or as a result of human activity. All solid, liquid or gaseous substances changing the average atmosphere composition are considered atmospheric air pollution. The introduced pollutants into the atmospheric air can have harmful effects on human health and its surroundings if their content exceeds certain acceptable values. In large clusters with dense buildings, due to specific urban and meteorological conditions, there are threats of exceeding the permissible levels of concentrations of pollutants in the air and the formation of smog. The improvement of air quality is related, among others, to the use of high quality carbon fuels for heating purposes. The quality of coal as such does not solve the problem without the use of appropriate modern thermal installations, especially in the municipal and living sector. However, the use of high-quality ecological coal is an appropriate action in the direction of air protection. PGG S.A. has a system for monitoring and controlling the quality of coal, ensuring the placing on the market of coal with high quality parameters, including ecological assortments for the needs of customers from the municipal and household sector. All coal fuels offered for this sector fulfills current quality requirements related to air protection. It is essential that the combustion of high quality coal takes place in appropriate, adapted to this, effective modern domestic boilers.

Simulation of the non-linear summation effect due to subsequent mining extraction using the theory of cellular automata


Abstract: The paper presents an example of real subsequent hard coal mining in the seam 338/2, which caused the formation of a subsidence trough on the surface of the mining area which after extraction of the longwall No. 2 was characterized by a significant asymmetry. Surface deformations were covered by systematic leveling measurements along the measurement line “1”. For the illustrated example of underground mining, numerical calculations were made using the theory of cellular automata. A non-linear transition function was used. Calculated data were compared with the results of geodetic observations. The aim of the article was to verify the theoretical assumptions of the model and to demonstrate the practical possibilities of applying the method to assess the subsidence of the mining area.

The importance of the filling of the goaf with fine-grained waste for safe operation of longwalls with caving


Abstract: Filling of cavings (goaf) is currently the most widespread technology of filling underground voids in Polish coal mining. Obtaining optimal results in the area of elimination of spontaneous ignition of coal remnants in goaf and other benefits in terms of climatic and ventilation conditions requires subsequent continuing of filling operations and use of mixtures with appropriate concentration of solids. Obtaining the effects related to limiting the deformation of the rock mass and surface subsidence is also achievable, however, it requires the use of mixtures with a high concentration of solid parts and a multi-point mixture placement system, which practical solution is a system of trailing pipes behind the hydraulic shield supports in a longwall. The article also presents the legal basis for the use of industrial waste in underground technologies as well as the necessary elements of the technical and operational documentation for the technology of filling of cavings.

Analysis of operating costs of the main coal mine dewatering system


Abstract: The main mine dewatering system is an essential element in the exploitation of underground mining plants. The system consists of many elements such as water channels and water walkways, underground tanks, powered pumps, and discharge pipelines. The operation of this system is independent of the current extraction, constituting a fixed cost of maintenance for the mine. Depending on the depth of the mine and the average inflow of water, this cost consists of the cost of electricity supplying the pump, the cost of depreciation of equipment, the cost of service and the costs of possible water disposal along with environmental charges. The article presents considerations regarding the reduction of main drainage operation costs through appropriate equipment operation and appropriate repair policy. The presented results are based on a real analysis of the functioning of the drainage system of one of the Polish mines.

The earth magnetic field in granite blocks cutting process


Abstract: This document reports on the problem of magnetic fields during the preparation of granite blocks. The most prominent problem consists of the use of long, thin cutting tools by which the magnetic field introduces detours in the cutting-process, losing more than 15% of granite block as raw material. In order to avoid or minimize the effects of magnetic fields, the magnetic orientation of the industrial building must be considered and the true deviation produced by the field must be calculated. On the contrary…, what happen when the workshop is built without magnetic considerations?. First of all we need to know and separate the effects of fields. In marine terms, this problem consist of calculating the total correction due to the effects of true magnetic field (δm) and deviation (Δ). Like a vessel navigating around the earth, the true course is the addition of two terms: compass course (magnetic) and effects of total correction (δm + Δ) where it is produced by the total metal mass around me and δm is the magnetic field of the earth in this point. We are going to calculate the total correction (ct).

Verification of S. Knothe theory parametres values for the region of intense, multi-seam mining exploitation


Abstract: The article presents the results of the analysis of measured deformations of the surface of the mining area in the region of the impact of very intense, long-term and multi-seam exploitation conducted by the "X" and “Y” mines in the field “K”. This analysis showed that the impacts in conditions of a very strongly deformed rock mass do not differ significantly from the impacts observed in conditions of less intensive mining exploitation. However, they are characterized by a slightly higher coefficient of variability of analyzed deformation indices than in other regions of USCB.
