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.

Abstract: The implementation of the strategic acoustic maps or evaluation of traffic investments interactions entails the necessity of modelling the traffic noise sources and calculating the emission of acoustic source. The modelling of the traffic noise seems to be the complex matter owing to different methods of modelling the road geometry (e.g. the number of roads and lines) and the possibility of application different methods of calculation. Mentioned factors significantly affect the accuracy in received results. The article below presents the course and the results of the scientific experiment, which main aim was analyzing the impact of different ways of modelling the traffic noise sources and the influence of the applied method of calculation on the accuracy in calculations of road acoustic emission. With particular precision there were explored the results obtained with the use of French calculating method NMPB Routes 96 recommended by The Directive 2002/49/WE for traffic noise calculations.

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: 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.

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.

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 research was conducted in a commune near the Polish-Czech border.

Determination of the influence range of exploitation pressure ahead of longwall face by the seismic profiling method

Abstract: Cyclic seismic investigations have been performed in the haulage inclined drift drilled in coal seam no. 510, during approaching of face of the longwall with caving no. 506 in the same coal seam. Performed investigations enabled determination the changes of velocity and attenuation coefficient of seismic P-wave in coal seam with the shortening distance between the longwall face and the inclined drift. With the use of the measured velocities of seismic P-wave, the changes of stress level in coal seam no. 510 were determined. The distance between the longwall face and the inclined drift, with the observed increase of stress level in coal seam no. 510 in the area of inclined drift due to the influence of exploitation pressure coming from longwall no. 506, has been determined. The study results should be useful to design the zones of the enhanced rockburst hazard in similar geological and mining conditions.

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.
