Abstract
A method of concurrent degassing carbonic rock mass of operating mines includes drilling wells, laying above a coal bed of a degassing collecting groove and gas extraction. The wells are drilled with a horizontal directed end toward the lava shearing. Degassing the carbonic rock mass is carried out after the shift of a gas-saturated coal during its production and gravity discharge of rocks of top of bed. First is drilled a vertical well bore and performed its transition for bending, from which above the top of coal bed toward shearing by second working lava a directed horizontal branch is drilled as a degassing collector followed by suction through it of coal gas layer and transfer through a shaft for further recycling.
