Opis:
The aim of the article is to present the results of laboratory analyses determining the content of rare earth elements (REE) in hard coal type 31.1. Coal was extracted directly from the mining excavation located in the Upper Silesian Coal Basin. Mass spectrometry tests with ionization in inductively coupled plasma (ICP-MS), were aimed at the quantitative analysis of the share of REE in coal, taking into account the economic aspects of recovery of these elements. Fine ground hard coal samples and ashes obtained after coal burning were assessed for the rare earth elements concentration. Results of the rare earth elements concentration (lanthanum and cerium) in hard coal are similar in the values obtained in previous tests. The current analyses present higher concentration of europium or neodymium. The article also contains the concept of possible future research work, consisting in the recovery of rare earth elements using, among others, a classifying hydrocyclone.

Opis:
The primary objective of this paper is to present a model of a process management system developed to support the restructuring of Polish enterprises of the hard coal mining industry. The development of this model required research in three stages using several research methods. The stage I of the research was oriented towards the recognition of the existing state of knowledge in the scope of previously developed models of process management in enterprises. At this stage, a method of reviewing the literature, the analysis and synthesis of the results of considerations, was used. The stage II was oriented towards presenting of the current state of knowledge in the field of process management to the managerial staff of mines in order to identify their needs, capabilities and preferences. The research were attended by 24 managers from PGG SA and JSW SA. At this stage, the method of targeted free-form interview and discussions, was used. The stage III of the research was oriented towards the development of a process management system model in enterprises operating in the hard coal mining industry, based on the scientific achievements to date in the field of process management and consensus on the needs, preferences and capabilities of mine managerial staff with regard to its specific elements. At this stage, the method of analysis and synthesis was used. The results of the research presented in this publication are primarily addressed to the managerial staff of polish hard mines, as they provide a synthesized response to the problem of the lack of consistent process management guidelines that could set a standard within a mining enterprise. The model presented in the publication is of a general nature, although it may provide a basis for the application of process management for mines.

Opis:
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.
Artykuł zawiera analizę procesu głębokich i wszechstronnych przemian strukturalnych przedsiębiorstw pozyskiwania węgla kamiennego w świecie, podjętych w konsekwencji szoku cenowego na międzynarodowych rynkach ropy naftowej i gazu ziemnego w latach 1973-1980 oraz wprowadzania kryteriów rozwoju zrównoważonego i trwałego od początku lat osiemdziesiątych XX stulecia. We wstępie sformułowano cel restrukturyzacji na poziomie mezo- i mikroekonomicznym, zidentyfikowany jako uzyskanie i/lub utrzymanie pozycji konkurencyjnej sektora, regionu lub przedsiębiorstwa w skali międzynarodowej. Scharakteryzowano najważniejsze czynniki, dostosowujące działalność producentów węgla kamiennego do zmian wielkości i struktury popytu, wynikających z nowych uwarunkowań technologicznych, środowiskowych i ekonomicznych użytkowników, a w szczególności: • międzynarodowy transfer wiedzy, innowacji i technologii w procesach pozyskiwania i wzbogacania węgla; • proeksportową orientację założeń planistycznych i projektów zagospodarowania nowo odkrytych złóż; • rozwój infrastruktury transportu węgla kamiennego z regionów górniczych do portów eksporterów; • międzynarodową współpracę producentów górniczych z odbiorcami węgla oraz firmami pośredniczącymi, opartą w szczególności o platformę jaką tworzy World Coal Association. Głównym wnioskiem zamieszczonym w podsumowaniu jest stwierdzenie, że w efekcie przedsięwzięć restrukturyzacyjnych, zrealizowanych w globalnym sektorze węgla kamiennego w latach 1980-2015, produkt ten utrzymał konkurencyjną pozycję w gospodarce światowej jako pierwotny nośnik energii oraz surowiec przemysłowy.

Opis:
In this paper we discuss the possibility of increasing service life of tools used in forestry for mulching of undesirable forest growths. In a heterogeneous working environment in which they are operated, such tools are subjected to constant abrasion and impact loading. There are several ways how to extend their service life and operational fitness. One of these is hard surface treatment, or hard surfacing of their functional surfaces. In our experiment, we chose suitable hard surfacing materials and applied these on the sample materials using the MMA and MAG welding. The hard surface was applied in an one layer. Subsequently, we performed hardness tests, microscopic analysis of the structure of the basic material and the hard surface and evaluation of the fusion penetration of the base material with the hard surfacing weld. Fusion is crucial as it determines the cohesiveness of the weld and base materials and thus also the actual extension of the service life of the tools.

The article presents problems related with exploitation of hard coal beds in the conditions of methane threat. There were discussed methods of identification of the levels of threat during the geological exploration works and designing of prospective exploitation. There was also presented the impact of conditions of retention of the bed on methane threat and possibilities of influencing the level of threat by appropriate selection of the method of ventilation of the wall’s neighbourhood. The role of automated and manual measurements and its impact on the level of threat was indicated. There was also discussed the use of waste gas (methane) in order to lower the level of the threat and simultaneous gaining economic profit from it. It was indicated that the increase of efficiency of the methane drainage is the best method of preventing its escape to the atmosphere.

Komputerowe systemy wspomagające zarządzanie eksploatacją maszyn i urządzeń oraz utrzymaniem ruchu w przedsiębiorstwach, z powodzeniem znalazły zastosowanie w wielu gałęziach przemysłu. Na przestrzeni ostatnich lat systemy te ulegały istotnym przeobrażeniom. Nieuchronnym wydaje się również, wprowadzenie tych systemów do obsługi maszyn urabiających w kopalniach węgla kamiennego, gdyż utrzymanie ciągłości ruchu generuje wysokie koszty produkcji. W przypadku ich wdrożenia, systemy te pozwolą na optymalizację zapasów magazynowych, części i materiałów, zaopatrzenia, usług zewnętrznych oraz prac konserwacyjno- naprawczych. Wykorzystanie systemu wspomagającego zarządzanie maszynami górniczymi, umożliwi również lepsze, bardziej efektywne wykorzystanie pracowników. W wyniku tych działań, skrócony zostanie czas potrzebny na przygotowanie i realizację napraw, co przełoży się bezpośrednio na efekty ekonomiczne kopalni.
Computer systems which support the management of equipment use and maintenance in enterprises have been successfully applied in many branches of industry. Over the last years these systems have become considerably transformed. Also their use in the operation of winning machines in hard coal mines seems inevitable, as productive maintenance generates high production costs. If implemented, these systems will enable the optimization of stocks, parts and materials, supply, outsourcing and maintenance-repair works. The application of a system for supporting the management of mining equipment will also enable a more effective use of employees. As a result, the time needed for the preparation and repairs will be shortened, which will directly translate into the economic results of a mine.

Opis:
This paper deals with the problem of defining the optimal procedure for reparation of the machine parts of large dimensions and complex shapes. The procedure consists of establishing the causes of the part's damages, definition of the reparation technology, with selection of its parameters and ways of execution. The reparation is done by hard-facing, with heat treatment that consists of preheating, additional heating and the post hard-facing tempering. The process parameters' selection includes choosing the right filler metal(s), ways and order of depositing the hard-faced layers, ways of reaching and maintaining the preheating temperatures, checking of the base metal's chemical composition and mechanical properties and deciding on the post-process heat and mechanical processing of the executed hard-facing. The executed reparation of the forging hammer's mallet, presented in details, serves as an example how the reparation can successfully serve as a substitute for procuring the new part and thus producing the savings both directly in lower costs and indirectly in shortening the down-time of the damaged part operation.

Opis:
In the majority of Polish mines, the exploitation of hard coal is accompanied by the release of considerable amounts of methane. Being flammable and explosive, methane may form an explosive mixture with air once it appears in mine workings. For this reason, the methane hazard is recognised as one of the ventilation risks in the mining industry. This process leads to the formation of air and methane mixture, whose considerable amounts permeate into the atmosphere and the natural environment. This phenomenon is extremely unfavourable because methane is, besides carbon dioxide, yet another gas that exacerbates the greenhouse effect. For this reason, it is increasingly more common to equip mines with methane collection systems in the process of demethylation. These play a vital role for both the natural environment and the safety of work in mines. A reduction of the methane content in headings increases the safety of the working crew and enhances the effectiveness of mining production. The article presents an analysis of the methane-related hazard based on methane emissions during mining exploitation. The analysis was based on the data concerning the amount of methane emitted into the atmosphere and collected by methane extraction systems from 16 coal mines. It led to identification of homogenous mines with similar values of the absolute methane-bearing capacity and ventilation methane-bearing capacity as well as with similar amounts of methane collected by methane extraction systems. The analysis was performed using the non-hierarchical k-average method, which belongs to the group of algorithms for analysing clusters. As a result, the mines were divided into the assumed number of groups. The results obtained made it possible to determine a group of mines in which, in the Author’s opinion, similar systems can be applied for controlling and reducing the methane hazard. These results also open up numerous possibilities for undertaking joint business ventures by the mines in terms of using the collected methane and implementing preventive measures.

Opis:
The main task of the maintenance services in hard coal mines is to ensure continuous operation of the equipment (machines). The measurable effect of these actions should be the reduction of maintenance costs of equipment (machinery) and thus the reduction of production costs - coal mining. The paper presents an issue of failure rate of technical measures applied in the mining process. In order to ensure greater efficiency and productivity, it is necessary to find the causes of the most frequent failures in this process and effectively counteract them. As a result of these activities, the production availability of machines/equipment involved in the mining process will increase. This will to a large extent ensure failure-free and uninterrupted progress, increase productivity and improve the quality of manufactured products, as well as reduce the operating costs of equipment (machines), and thus reduce production and product costs. This effect should consist mainly in the control of rational, safe and effective use and operation of equipment (machines) in the exploitation process. An algorithm implemented in one of the hard coal mines was presented. The technical condition of underground mining equipment was observed by periodical measurements of vibration parameters at selected points on the machine - measurements were conducted with a vibration pen. The aim of this research is to improve the reliability of technological process of a mining plant through its failure-free operation. In order to achieve this objective, i.e. the efficiency of a mining company, it is necessary to reduce its costs. The action that leads to this aim is a proper assessment of the technical condition with regard to the equipment used in technological process.

Opis:
The article presents the current topic of the possibility of mechanical extraction of hard and abrasive rocks using mechanized wall systems. The problem of extracting ores from thin strata precludes the possibility of further use of current technologies involving a human at the face. Currently, the operation is carried out using explosives in column-pillar systems. In systems with a chamber column, all major processes are mechanized and carried out by self-propelled drilling and bolting machines, loaders as well as hauling and auxiliary trucks. These machines are operated in the workplace by operators. For many years, effective mechanical excavation methods were sought that would allow the development of a mining machine and a mechanised longwall complex. Such a complex is to allow excavation without the presence of humans at the face. The article presents the current technical capabilities, assumptions and requirements for such a solution. Then, an innovative longwall complex equipped with a disc shearer is introduced. The technology of work and achievable productivity are briefly presented. A worn shearer, a face conveyor and a powered support are the subject of AGH inventions.

Opis:
This article presents a pilot study on the local community’s social perception regarding coal mines in Upper Silesia. The research was performed in connection with the smog, which was persistent and harmful to residents during the winter months of 2016. The researchers put forward to the local community the following two survey questions: 1. Is the image of coal mines in the eyes of the local community positive or negative? 2. Are coal mines socially responsible and is coal a good energy source? The aim of this article is to indicate the relationship of the local community to the presence of hard coal mines in the neighbourhood and their social role. Also, this work looks to identify the nuisances perceived by the inhabitants of the examined region about mining enterprises and whether these burdens should result in abandonment of hard coal mining. Pilot studies were conducted with the use of a diagnostic survey. The study was carried out in January 2017 on a sample of 267 people, comprising Silesian University of Technology students residing in Upper Silesia. An environmental survey technique was used. The researchers hypothesise that the image of mining and coal as a fuel for the local community is negative and the mines are not socially responsible enterprises. This research shows that the operation of mines is essential for society and its stability as it affects economic, social and energy safety. A large proportion of the respondents defined the image of mining as positive (108 people), but 76 people indicated that the image was rather negative. Most respondents pointed to the benefits of the mine’s operation. Opinions on social responsibility were divided, and most respondents failed to provide concrete examples of social engagement, so the first hypothesis was partly confirmed. Although the respondents pointed to various nuisances resulting from the mining companies operating in their environment, they also recognised significant social aspects related to employability and access to relatively cheap fuel. However, they do not realise the social involvement of mines, which is one of the conditions of sustainable development. Pilot studies allowed for the initial identification of problems and verification of the research tool utilised in this study.

Opis:
In hard coal mines with methane, there is often a need to apply demethylation in order to keep the methane concentration not exceeding 2% in the ventilation air. The basic demethylation method in longwall areas is through drainage boreholes made in the roof rocks of the coal bed, from top gate, in front of the longwall. The drainage boreholes are usually made in bundles, in a fan-shaped arrangement, with several boreholes in each bundle. The paper presents the results of measurements and tests of the efficiency of a bundle of four drainage boreholes drilled approximately 100 m in front of the longwall face. The efficiency of individual boreholes was analyzed in time and depending on the distance of borehole outlets from the longwall face. It was found that there is a large variation in the extraction of air-methane mixture by individual drainage boreholes, as well as large differences in the efficiency of individual drainage boreholes during the longwall extraction process.

At present the products of the MBE-CMT, Allmineral and Tenova companies have big market shares as regards foreign water pulsatory jigs, as well as ITG KOMAG on the local Polish market. New implementations of jigs, developed at the KOMAG Institute of Mining Technology, for beneficiation of coking coal and steam coal in collaboration with Carbo-Eco Ltd. and Fugor Ltd. companies, were realized in 2019. Technical and technological parameters of new devices are described in the article. Supply systems of feed are presented as well as the method of collecting tailings and middlings. New design solutions, applied in modernized preparation plants, aimed at an improvement of jigs production capacity and efficiency are presented. In the case of each jig, after its activation and conducted adjusting processes, exact tests of a beneficiation efficiency were performed and their results are presented in the tabular form. Basic beneficiation accuracy indicators and parameters of products’ separation as well as balances of products are given. The test results, obtained from newly activated jigs, are discussed.
