dc.descriptionRecent world trends have shown that a country’s political security depends on its fuel and energy supply. In Ukraine, these issues are managed by the United Energy System of Ukraine (USE). The USE consists of a set of power plants as well as electric and thermal networks operating in the general mode of production, transmission and distribution of electric and thermal energy. Nuclear power plants (NPPs), thermal power plants (TPPs), hydroelectric power plants (HPPs), thermal power plants (CHPs), as well as power plants run on alternative (renewable) sources of electricity (solar, wind, bio- and others). They are operating in one system. All of them are connected by the main electric networks. Thermal power plants (TPPs) produce nearly 27% of all electrical energy in Ukraine [1]. Recently, the amount of commercial coal required by Ukraine’s energy sector has increased from 19 to 21 million tons. In 2021, coal production had decreased by approximately 7.7% compared to 2020. Accordingly, this requires the import of coal [1]. Therefore, increasing the efficiency of coal mining is an urgent scientific and practical task.uk_UA
dc.description.abstractUkrainian electricity production sector is in a critical situation. It is necessary to increase the coal production to ensure the continuity of electricity production. In this paper, an analysis of coal mining in western Donbas, Ukraine, was presented. The crucial thing is to increase coal production in this region. The new calculation schemes were proposed to increase coal extraction in Donbas mines. The coal pillar parameters, which are necessary for the effective control of the rock pressure caused by the stooping, were substantiated. The obtained parameters for the coal pillars will allow extracting more coal, safely and quickly dismantling the mechanized complex and effectively protecting the ongoing mine work. The case study helps determine the coal losses because of pillar leaving and to improve the stability of the main haulage roads located in the zone of the stooping effect as well as to achieve additional coal production in the mine. Such a technological solution allows to extract the coal more fully at the final parts of the extractive columns and to obtain an additional economic effect. The increase in coal production in coal mines of western Donbas will increase the energy security of all Ukraine.uk_UA
