. Nowadays, in connection with the difficult situation with energy supply, the implementation of cogeneration technologies using mine methane is becoming of urgent importance. Solving the issue of extracting mine methane as an alternative energy source is of great importance. The article substantiates and develops a method of methane extraction from distant thick layers of sandstone. The idea of the work is to use the laws of forgery and filtration properties of thick layers of sandstone (more than 10 m) distant from the developed layer, which is a gas collector, for the purpose of extraction and further use of methane as an energy resource. The use of the proposed method of methane extraction will allow increasing the safety of cleaning operations, solve the issue of methane utilization and improve the environmental situation in the industrial region. According to the developed method of methane extraction from distant thick layers of sandstone, degassing is performed by underground wells. Capturing the methane-air mixture is carried out using a vacuum pump station, which is located on the main industrial site of the mine. To ensure the company's own production of electricity and thermal energy, a gas-piston cogeneration power plant was chosen. As a fuel, mainline natural gas with an average supply pressure or methane mine gas is used. The basic configuration of the power plant is a gas piston engine with a liquid cooling system. In order to obtain a gas-air mixture of the required concentration (from 25% to 40%) at the vacuumpump degassing station, a methane concentration increase installation is planned.
