Abstract
The methods of geomechanical ensuring development gas-bearing coal seams has been developed. The method of borehole mining of coal and gas from formations prone to gas and geodynamic phenomena has been scientifically substantiated and developed. Safe mining operations are ensured through the use of the internal energy of the rock mass to fracture the mineral in borehole production and its transportation to the consumer. The hydraulic mining method of sweet gas-bearing coal seams has been developed. As degassing is used preliminary unloading of coal beds and rocks by borehole coal mining from the reservoir, hazardous gas emissions. In general, the method of controlling geomechanical and gas-dynamic processes ensure the safe and efficient development of gas-bearing coal seams.
