In Poland, this means moving away from the extraction and use of coal. The Social Contract for the Mining Industry signed in 2021 states the necessity of last mine closure by 2049. Mine closure is a complex, lengthy and costly process. A complex scientific solution may concern the use of rational operations and minimi-zation of mine closure costs. This article presents a system for the elementary assessment of the potential time and cost of coal mine liquidation. Estimating coal mine closure costs in the early design phase is an key aspect of supporting the company dealing with mine closure. The aim of the research was to improve the tool for assessing mine liquidation price. The extended assessment solution proposed in the article is formed on base of statistics of past mining institution liquidation processes. This method can, with minor modifications, be used for each restructuring and revitalizing task for mining industries in the process of liquidation. At the core of the developed method is a preliminary data analysis, which should be confirmed by a complex and multi-criteria estimation of the costs of the planned mine liquidation.

A comprehensive scientific approach may facilitate the rationalisation and minimisation of mine closure costs. This study proposes a method for the preliminary estimation of the costs and time required for the potential liquidation of a hard coal mine. In addition to a literature review, a statistical analysis and a case study, personal interviews were conducted with individuals with direct management over the restructuring, reclamation and liquidation processes pertaining to mines undergoing closure.
The assessment method is based on an analysis of the mine liquidation costs, divided into successive years of the course of the aforementioned processes. The method does not pertain directly to the specific liquidation processes conducted at SRK S.A., therefore it can also be employed by any entity conducting mine liquidation as a comparative tool for the detailed and multi-criterial estimation of the costs of planned mine closure.

mines can be harmful and even dangerous to health, contributing to body dysfunction and health issues.
Overloading the body decreases physical fitness and work efficiency and increases the risk of health
and life-threatening events. This study analyzed the practical possibility of reducing the body
temperature of mine operators under harsh climatic conditions using cooling vests. The results showed
the usefulness of cooling vests in daily work despite the need to replace cooling cartridges during work
shifts.

A complex scientific approach will facilitate the conduction of the management of costs of hard coal mines liquidation. An analysis of the costs of the mine’s liquidation was carried out on an annual basis with the division for subsequent years of the course of processes. The presented method of signalling costs that has gone beyond the structure of acceptable values developed for 20 years of operations of SRK S.A. is a useful tool for the cost management in the field of mining plants liquidation. Not only the method can be used for the initial costs’ estimation of mining plants liquidation, but it can be used as a cost management tool as well. After some modifications, the method can be also used by any enterprise conducting the management of assets of mines put into liquidation as a comparative tool for multi–criteria cost estimation of planned mines liquidation. The tool may increase the efficiency and effect...

Obtaining methane from goafs can bring financial, ecological and social benefits for many years. In areas where mining activity is reduced, any potential way to restore workplaces should be considered. The possible variants of technical solutions were presented and the conclusions resulting from each variant were indicated. Optimal variants were selected from the proposed liquidation variants by means of single-criterion and multi-criteria analysis. The analysis showed the main factors influencing the course of the mine liquidation and methane drainage process.

The results of the research on the COVID-19 pandemic on the functioning of the mine restructuring company Spółka Restrukturyzacji Kopalń S.A. (SRK S.A.), which is the body whose main goal is the mine liquidation process, are presented. Restructuring activities have been carried out in the Polish mining industry since the end of the 20th century so as to adjust the industry to the market economy. The liquidation of the mine is the last and natural stage of mining activity. The investment process leading to the liquidation of the mine is complex and costly. The changes that are taking place in the mining environment caused by the pandemic of Covid-19 cause both current and long-term economic effects in the operations of most economic entities. The publication analyzes the implementation of the restructuring processes in a closed mine. Th...

The activities related to the revitalization and restructuring of hard coal mines are carried out by Spółka Restrukturyzacji Kopalń S.A. (SRK S.A.), as the legal successor of previous mining operations. The implementation of the mine liquidation process has not been the subject of scientific research so far aimed at rationalization and minimization of the costs incurred. Activities leading to the liquidation of the mining plants are the procedural nature, however, the mine liquidation is always a single case which has a result in diversifying the size of outlays. The support for the implementation of the process approach in the issue of mine liquidation in terms of rationalization and minimization of the costs incurred in SRK S.A. was to develop a method of managing the costs of liquidation processes with the software for evaluation of its size. The proposed method signals to the designer that the estimate...

The procedure and conclusions which are 8 presented will be the base to ensure effectiveness and efficiency of the processes of the 9 liquidation. 10 Design/methodology/approach: To create a model of the process management systems in 11 SRK S.A. three stages of research were achieved. The available literature on the management 12 processes was analyzed and compared with personal experience of the mine liquidation. 13 Interviews were conducted with the Branch Management of SRK S.A. The maps of the process 14 of the liquidation were prepared and the areas and problems of the research were shown. 15 Findings: The respondents wanted to have prepared the process flow maps, that will facilitate 16 the conduct of current and possible future liquidation processes in terms of financial efficiency. 17 Research limitations/implications: An analysis and...
