FIELD: mining.
SUBSTANCE: method includes drilling of degassing wells in a processed massif perpendicularly to direction of breaking face movement, performance of hydraulic ruptures of a coal bed from them and subsequent gas pumping. At the same time degassing wells are drilled as through with the lower mine to the upper one, and hydraulic ruptures are carried out by movement of a drilling rod in a reverse direction.
EFFECT: increased area of gas release and reduced time of degassing works.
