ЭКОНОМИЧЕСКАЯ ЭФФЕКТИВНОСТЬ ЗАБЛАГОВРЕМЕННОГО ИЗВЛЕЧЕНИЯ МЕТАНА ИЗ УГОЛЬНЫХ ПЛАСТОВ В СОВРЕМЕННЫХ УСЛОВИЯХ

Abstract

One of the key problems of the coal industry in the modern world is the effective degassing and elimination of methane and other gaseous impurities from the developed seams. A high concentration of methane has a negative impact not only on the performance of the mine, but in case of significant excesses, it can lead to a stop in production. Coal mining companies are losing significant financial resources to restore the working capacity of mines and utilize gas impurities, meanwhile, more and more experts are turning to early degassing, which allows you to get rid of most of the natural gas even before the field is put into operation. The purpose of this work is to identify and analyze modern tools for early degassing of coal mines in Russia, taking into account sanctions restrictions on the import of foreign equipment, as well as economic instability in the international energy market. Utilization of methane with early degassing is possible not only by “standard” methods of emission into the atmosphere and flaring, but also by direct use both in the production itself in the generation of heat and electricity, and with subsequent transportation to the end consumer. This method increases economic efficiency and allows to provide power supply to the developed field without connection to the central networks. Also, early degassing has a positive effect on safety and reduces the risk of accidents involving people. The scientific basis of this study was Russian and foreign opinions and assessments of industry experts, statistical data of companies in the fuel and energy complex of Russia, information on patents and import substitution of foreign equipment in the coal industry, federal and regional regulatory databases.
