FIELD: mining engineering.
SUBSTANCE: invention includes implementation of mine openings, drilling from chamber in the range of block of treated layer of overlength underground wells in the direction of connection development, sealing of its mouths, connection to gas conduit and suction of methane. Novelty of invention is that from chamber there are implemented through wells, curvature of which from mouth in the direction of boring is reduced up to zero, herewith through wells are sealed from both sides, suction of methane at the first stage is implemented in two directions, and at the second stage of implementation of second workings methane is sucked off in the direction of upset excavation.
EFFECT: there is achieved extraction of high volumes of methane from coal bed with withdrawal of it from mining face, reduction gas-ample of mine openings, providing of safe working conditions of miners by gas factor in process of implementation of minings, reduction of appearance probability of methane explosion and carbon dust, improvement of economic indexes of mine and air atmosphere.
