Purpose. To establish the optimal parameters of the bench elements and slopes of the pit at the mining of Horishne-Plavnynske and Lavrykovske deposits of ferruginous quartzites for further use of these parameters at the design. Methodology. Methods for determining the influence of the bench height on the productive pit capacity involves taking into account the quality of the ore, the rate of the mining front advancement, the rate of pit depth at the mining operations, the total length of the mining front, as well as the angles of the working and non-working pit slops. Findings. The most effective parameters for mining benches and slopes of an iron ore pit are considered, using the example of the Ferrexpo Poltava Mining. Parameters of the bench elements with a height of 2430 m have been established, which are worked out in layers with a height of 12, 10 and 15 m. The studies carried out made it possible to establish that layers with a height of 10 m, followed by the final and temporary pit contour with a bench height of 30 m, can improve safety due to the flattened slope of the pit up to 45, while, with a bench height of 15 m, the angle of inclination of the slope will be 47. Originality. The established dependence of the pit ore productivity in percentage on the bench height suggests that with an increase in the bench (layer) height, the ore productivity of the pit decreases. Determination of the influence of the working bench (layer) height on the total volume of ore losses in the design contour of the pit makes it possible to assert that at constant angles of the bench slope and the ore deposit fall, the values of operating losses and clogging change in direct proportion to the height. Practical value. A technological scheme has been developed for the development of a bench with a height of 30m with a layer thickness of 10 m, which makes it possible to improve safety in the pit by pit slope flattening to 45, to reduce the cost of ore mining by optimizing drilling operations (shorter drilling time per well, reduction of overdrilling and etc.) and thereby improve the economic performance of the enterprise.

“…Before underground thermal energy storage constructing, it is necessary to carry out a detailed hydrogeological analysis, taking the stratigraphy, the location of groundwater tables, soil permeability, and the size and direction of groundwater flows into account (Wyrwicki 2004). Different hydrogeological conditions must be met for each type of underground energy storage (Dychkovskyi et al 2019;Mangold and Deschaintre 2016;Matuszewska et al 2020).…”

The objective of the European Green Deal is to change Europe into the world's first climate--neutral continent by 2050. Therefore, European countries are developing technological solutions to increase the production of energy from renewable sources of energy. In order to universally implement energy production from renewable energy sources, it is necessary to solve the problem of energy storage. The authors discussed the issue of energy storage and renewable energy sources, reviewing applied thermal and mechanical energy storage solutions. They referred to the energy sector in Poland which is based mainly on mining activities. The method that was used in this paper is a review of thermal and mechanical energy storage solutions. In industrial practice, various solutions on energy storage are developed around the world. The authors reviewed those solutions and described the ones which currently function in practice. Hence, the authors presented the good practices of energy storage technology. Additionally, the authors conducted an analysis of statistical data on the energy sector in Poland. The authors presented data on prime energy production in Poland in 2004-2019. They described how the data has changed over time. Subsequently, they presented and interpreted data on renewable energy sources in Poland. They also showed the situation of Poland compared to other European countries in the context of the share of renewables in the final gross energy consumption.

“…Water pass throughout the wells, which lower mouths are equipped with hydroturbines with generators, transforms the kinetic energy of water flows into the electric one. Such a mine micro-HES consists structurally of the pass well reinforced with pipes; hydroturbine; generator; automatic systems to stabilize the output pressure and the flow start and stop; and a series of stop and ballast valves and other elements [21,25]. Increase in the energy capacity of the flow will depend on the water level heads.…”

The paper represents the analysis, which has helped to determine tendencies of the formation of energy resource complex based on the available mining facilities. The approach helps prolong operating life of the mine with the depleted balance reserves or the one being under abandonment. The proposed technologies of generator gas production by anaerobic digestion of organic raw material in the methane-tanks as well as other approaches to the combined formation of new energy systems make it possible to reorient the mine operation. The approach is extremely important for rather depressed mining regions as it helps solve the problem of social strain. Formation of the joint power and chemical production allows both improving economic expediency and preventing negative ecologic impact on surface and underground mine environment. The proposed tendencies make it possible to outline further issues to be highlighted in the following authors’ studies.
