METHOD OF DEGASSSING OF OVERWORKED ACCOMPANYING BED Russian patent published in 2018 - IPC E21F7/00 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry and can be used to solve the problems of reducing the gas saturation of gas-bearing working coal seams and coal-bearing strata. Method for degassing the adherent satellites includes the sinking of additional drainage workings along the worked-out excavation column along the gas-bearing formation-satellite at a distance from the processed formation. At that in parallel to the drainage workings, another drainage work is carried out, along the adjacent excavation site of the working layer. At that drainage workings are carried out along the lower maintenance satellite bed at the center of the future excavation pillars, connected with slots, and then ascending degassing wells drill from the workings. Wherein, the wells are not drilled to the developed reservoir.

EFFECT: invention solves the problem of increasing the efficiency factor of the degassing of the coal beds under repair.
