Abstract

The article considers the method of recovering structural integrity of operating degassing holes without outage and the scheme of cross-wise hydraulic fracturing in the hole-bottom zone using mechanical anchor. Advantages of the scheme with anchor are discussed as against directional fracturing with a slot initiator. The technical solutions on protection of methane drainage zone from air leaks from underground excavations are presented.
