Abstract
The technology of thick seam development with roof coal release on the face conveyor which allows increasing the coal flow, reducing the losses and stand-by-time of the stope is worked out by the Institute of Coal of FRC CCC SB RAS. Disintegration of roof coal preparing it for release can be done during gradual advancing of a stope or in advance, applying the method of interval hydraulic fracturing before starting stoping.
