“…This issue was considered through the prism of global examples and experiences of the use of mine water energy as one renewable energy source. Among the many inspiring solutions, one can distinguish a Netherlands project [11] leading to the creation of a sustainable energy node or the idea of the use of mine water heat in the Rostov region [78,79]. The authors are aware that the solutions currently presented are not an alternative, but a complement to existing solutions (stable role of fossil fuels [80,81]).…”

Background: Non-renewable energy continues to remain the main link in energy production in Poland. At the end of 2016, fossil fuels (hard coal and lignite) accounted for around 82% of gross domestic energy production. Reducing the share of fossil fuels in renewable energy sources in the overall energy mix is a long-term process. An example of solutions for the use of renewable energy sources as one of the key elements of sustainable development, ensuring rational, economical, ecological and social effects is the application of heat from mine waters for the production of thermal energy. The work estimates the current national energy balance in the country and describes the role of fossil fuels in the context of the issue of low emissions. Political transformation and accession to the European Union (EU) have contributed to greater care for natural environment. Poland, while being obliged to comply with the European guidelines, monitors the state of atmospheric air pollution and takes measures to improve its condition. Research issues presented in the article are addressed in the socio-environmental context. Methods: The method of reviewing scientific articles on the subject was used in the course of research task implementation (leading to the creation of a sustainable energy node or the idea of use of mine water). In addition, an analysis was carried out of the existing energy clusters in order to catch up with the standards of the European Union. Results: The analysis of world and national literature shows potential of using energy from the mining waters of active and closed mining plants. The authors propose the introduction of a precise term regarding mining potential as a thermal energy cluster. The opportunity to change the image of mines as polluters consists in using their potential beyond their main activity profile. Furthermore, the use of the hidden potential of mines signifies prolonging the life of an enterprise and thus, as its consequence, sustaining jobs and developing the region. Conclusions: The analyses presented in the article indicate the possibility of thermal energy production from mine waters not as an alternative but as an addition to the existing solutions, especially for the local needs.

“…Furthermore, the social costs of mining are analyzed [38][39][40]. Additionally, researchers evaluate the effect of by-product use on mining production efficiency [41][42][43][44]. The study of the environmental and social effects of coalmining allows researchers to evaluate the product life cycle (PLC) of coal [45].…”

European hard coalmining is a declining industry, despite the use of hard coal for energy in several countries. Industry restructuring and public subsidies have failed to stop this industry's decline. The largest hard coalmining sector, the Polish sector, has faced an obstacle to its survival: How to reduce production costs to compete with less expensive imported hard coal? This article aims to identify and analyze the dependence of the total production costs representing production and infrastructure parameters of the Polish hard coalmining industry. The parameters are divided into three groups: (1) the cost of employees and the production volume; (2) the number of longwalls, the length of a longwall, the daily longwall advance and the preparatory work advance; and (3) the number of levels in exploitation, the number of layers in exploitation and the number of shafts. The findings indicate that, even in well-functioning coalmines, there are many economically irrational relationships, especially regarding employment and infrastructure size. This study shows that employment, which is a significant cost component of the production and infrastructure parameters of the examined Polish hard coalmines, is not economically rational in terms of its proportion to the total production costs. As a result, even a considerable reduction in employment or infrastructure does not influence the unit costs of mining production, which could only be partially explained by the high level of fixed costs. There are also no appropriate relationships between infrastructure parameters and the total production cost. Under these irrational conditions, a reduction in the production costs of hard coalmining enterprises is difficult, but unproductive costly activities could prevent an improvement in production efficiency. Only restoring the proper relationship between economic and infrastructure parameters and the total production costs can ensure a return to price competitiveness. Those actions are crucial for the Polish hard coalmining industry, because the research focused on successful hard coalmines that were not declining indicate it should be able to implement cost improvements.

Taking reducing the wear of the fixed cone liner of a cone crusher as the starting point, the movement and geometry parameters of the cone crusher are studied using the discrete element method. To improve the service life and working efficiency of the whole cone crusher. The UG model and discrete element Yade model of the cone crusher are established, and the different shapes of the tin ore are represented using Yade’s preprocessor through eight different ways of particle combination and superposition. The static friction coefficient between the manganese ore and the cone crusher is studied and calibrated using the slope method. The relative error between the Yade and test results is 1.58%, and the calibration result is 0.44. The repose angle of the manganese ore is studied using the collapse method. The repose angle increases with the increase of the static friction coefficient and the dynamic friction coefficient, but the change trend is different. The effect of the dynamic friction coefficient on the repose angle is obviously greater than that of the static friction coefficient. The dynamic friction coefficient obtained by Yade is 0.042. Taking the swing distance, rotating speed, and bottom angle of the fixed cone as the orthogonal experimental factors of Yade, the regression equation of the fixed cone liner was obtained through the nonlinear processing of SPSS 25.0. According to Matlab R2017b, the influences of the swinging distance, rotating speed, and bottom angle of the fixed cone on the fixed cone liner are obtained. According to Yade’s research results, the order of the influence degree of liner wear is: the rotating speed of moving cone, the swinging distance of the fixed cone, and the base angle of fixed rotation. When the swinging distance of the fixed cone is 146 mm, the rotating speed of the moving cone is 198 rpm, the fixed rotation bottom angle is 28°, and the minimum value of the liner wear is 23 mm. Yade’s results are consistent with the change trend of the wear amount of the bushing obtained from the test. The research results show the correctness of using the Yade method to study the wear of the fixed cone liner of a cone crusher, which provides a theoretical basis for reducing the wear of the fixed cone liner of a cone crusher, and puts forward a new method to study the wear of relevant parts of a fixed cone crusher. At the same time, the research results are of great significance for achieving energy-saving in mining enterprises.
