A Multifaceted Method of Analyzing the Amount of Expenditures on Mine Liquidation Processes in SRK S.A.

Abstract

The liquidation of the mine is the last and natural stage of mining activity. 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 estimated cost of the process of liquidation of another mining plant deviates from the average values previously worked out by SRK S.A. The range of acceptable values results from the assumed coefficient of data variation.

The Impact of Two Years of the COVID-19 Pandemic on the Functioning of a Mine Restructuring Company in Poland

“…The branch carries out the tasks of Process 1 with the amount of 1.74% of its liquidation cost (Fig. 4) Chmiela et al, 2022). In 2020, as a part of Process 1, 13 km of mine workings was planned through the construction of 23 insulating dams and 1 explosion-proof plug.…”

“…2). Legal regulations oblige the branch to commission the development of projects, expert opinions or analyses to external entities, usually independent experts or institutions (Chmiela et al, 2022). The cost of process implementation in the branch decreases with the passage of time and the decreasing number of maintained facilities.…”

“…The branch plans to complete these procedures in 2022. Process 10 (General management of the tasks performed during the mine closure) lasts for the entire period of the operations of the branch from its establishment to its liquidation (Chmiela, 2022;Chmiela et al, 2022). According to the experience of SRK S.A. it is shown that the expenditures on Process 10 is one of the three largest components of the total cost of restructuring mining plants.…”

The Cost Reduction Analysis of Green Hydrogen Production from Coal Mine Underground Water for Circular Economy

“…The variant project in question will create new markets related to modern transport and an energy mix based partly on renewable energy [19,25]. The presented variants of energy self-sufficiency also provide the opportunity to revitalize post-mining assets, which would otherwise be difficult to adapt to another purpose [26][27][28].…”

Comprehensive Method for Estimating the Time and Expenditures Required for Mine Liquidation Processes of Business Processes

“…The prudent allocation of funds for the efficient management of post-mining areas has yet to be thoroughly studied in scientific research [22,23,24]. Carrying out mine liquidation is highly complex and expensive due to the extensive amount of work involved [25,26,27]. A key factor hindering improvements in liquidation efficiency is the absence of instruments and tools for cost management support [21,22,28,29].…”
