FIELD: mining.
SUBSTANCE: invention relates to mining and can be used for intensification of coal bed degassing by hydraulic fracturing method. Proposed method comprises well boring in well bed, cutting of initiating slot on its side surface, sealing of well rupture interval, injection of water under pressure into formation fracture interval and formation of fracture in rock. Coal particles formed during cutting of the initiating slot are retained in the interval of well fracturing, mixed with injected water and the obtained suspension is pumped into the fracture.
EFFECT: increased efficiency of gas-bearing coal beds degassing intensification.
