FIELD: mining.
SUBSTANCE: invention consists in drilling formation borehole, in its sealing, in pumping liquid (water) into formation in static mode, in hydraulic pulse effect on formation and in connecting borehole to degassing pipeline. The novelty of the invention consists in adding chemically active substance and substance, molecule of which has movable hydrogen into pumped liquid; also concentration of introduced additive is specified depending on contents of periphery hydroxyl and carboxyl groups in chemical structure of coal. Magnesium-iodine-methyl is added to water as a chemical substance. Magnesium-iodine-methyl is added with the organic compound containing hydroxyl or carboxyl group.
EFFECT: implementation of method facilitates increased contents of methane in mixture withdrawn from formation due to chemical reaction at reaction of magnesium-iodine-methyl with water and organic substances having chemical groups with movable hydrogen including these ones in chemical structure of coal.
