Special Issue Information

Dear Colleagues,

Mining has accompanied man for a very long time and is one of the key industries. For many years, mining has been a driving force and has also contributed to the development of other industries and new technologies. It should be noted that working conditions in mines are very difficult and specific. Consequently, the technologies and machinery used in the mines also required careful and appropriate thought and design. Nowadays the emphasis on development has shifted to other industries; however, new trends and modern and advanced solutions using technological achievements are still being applied in the mining industry. The applicability of simulation research supports the mining industry both in the design of new machines and the development of new technologies, as well as in the process of optimizing and modernizing existing machines and introducing automation in mines. Another aspect of modern mines is the use of numerous sensors and the development of a way to transmit signals. Thus, it introduces the possibility of optimizing the operation of machinery and predictive maintenance but also minimizing the number of necessary miners in the most dangerous areas. Another aspect of the application of modern technology is the aspect of monitoring and revitalizing the sites of waste generated by the production process. In the aspect of mine closure, especially in the context of the European mine closure policy, work is also being carried out to apply modern and innovative technologies to develop post-mining infrastructure.

Transformation of Coordinates of Boundary Points of Neighboring Mining Areas Using an Authorial Procedure Based on the Method of Independent Models—A Case Study

In order to integrate data relevant to decision making, especially for the development of post-mining areas, it is important to ensure their uniform spatial reference. A problem arises when the coordinates of the boundary points of mining areas of neighboring mines are documented in different local rectangular flat coordinate systems. It is then necessary to transform the coordinates of these points into a uniform coordinate system. The currently implemented coordinate transformations in Poland, which are implemented separately for each area, do not allow the obtainment of the equal coordinates of identical boundary points. Therefore, topological consistency in such areas is missing. This problem was the focus of the research carried out by the authors. An authorial transformation procedure has been developed based on the method of independent models, which makes it possible to obtain the equal coordinates of identical boundary points using the transformation procedure. This procedure is presented in this article. The results of the transformation of the coordinates of boundary points of 14 mining areas located in the southern part of Poland, i.e., in the Upper Silesian Coal Basin, are also presented in this article. This task was carried out using the previously used transformation, performed separately for each of the mining areas and in accordance with the authorial procedure presented in this article. It was found that the values of differences in the locations of identical boundary points of the areas after the execution of separate transformation ranged from 0.002 m to 1.945 m. The difference in coordinates Δx and Δy reached a maximum value of 1.937 m and 0.542 m, respectively. The differences in the coordinates of identical boundary points, using the method of independent models, reached a maximum value of 0.001 m, which basically resulted from the rounding up of significant figures. The above facts indicate the validity of using the solution proposed by the authors, allowing topological consistency in areas where it is necessary to integrate the spatial data of neighboring areas.

In Europe, renewable energy sources such as photovoltaic panels and wind power plants are developing dynamically. The growth of renewable energy is driven by rising energy prices, greenhouse gas emission restrictions, the European Union’s Green Deal policy, and decarbonization efforts. Photovoltaic farms generate energy intermittently, depending on weather conditions. Given the increasing number of new installations, ensuring the power balance and transmission capacity of the electrical grid has become a major challenge. To address this issue, the authors propose a technical solution that allows the energy generated by photovoltaic systems to be stored in the form of heat. Thermal energy from solar power and wind energy offers significant potential for energy storage. It can be accumulated during summer in specially designed sand-based heat storage systems and then used for heating purposes in winter. This approach not only reduces heating costs but also decreases greenhouse gas emissions and helps balance the power grid during sunny periods. Post-industrial areas, often located near city centers, are suitable locations for large-scale heat storage facilities supplying, among others, public utility buildings. Therefore, this article presents a concept for utilizing high-temperature sand-based heat storage systems built in decommissioned underground mining excavations. Full article
