Claims (4)

1. Способ подземной газификации свиты газоносных угольных пластов, включающий бурение скважин с поверхности, подготовку и розжиг подземного газогенератора по нижележащему угольному пласту с отводом генераторного газа и дегазацию вышележащего массива с отводом метана на поверхность и последующим смешиванием его с генераторным газом, отличающийся тем, что дегазацию массива ведут из зоны разгрузки одновременно с газификацией нижележащего угольного пласта, причем скважины для дегазации массива бурят с поверхности до почвы верхнего в свите угольного пласта с образованием над газогенератором газоулавливающего свода.1. The method of underground gasification of a suite of gas-bearing coal seams, including drilling wells from the surface, preparing and firing the underground gas generator on the underlying coal seam with the removal of the generator gas and the degassing of the overlying mass with the removal of methane to the surface and subsequent mixing it with the generator gas, characterized in that the degassing of the massif is carried out from the discharge zone simultaneously with the gasification of the underlying coal seam, and wells for the degassing of the massif are drilled from the surface to the upper soil in those of a coal seam with the formation of a gas catcher over the gas generator. 2. Способ по п.1, отличающийся тем, что газоулавливающий свод создают в породах кровли путем образования через пробуренные скважины трещин гидроразрыва, ориентированных в сторону пласта.2. The method according to claim 1, characterized in that the gas-collecting arch is created in the roof rocks by the formation of hydraulic fractures oriented through the drilled wells oriented towards the formation. 3. Способ по п.1, отличающийся тем, что газоулавливающий свод создают в верхнем в свите угольном пласте путем гидроразрыва его через пробуренные скважины.3. The method according to claim 1, characterized in that the gas recovery vault is created in the upper coal seam in the suite by hydraulic fracturing through the drilled wells. 4. Способ по п.1, отличающийся тем, что газификацию нижележащего угольного пласта осуществляют через вертикальные скважины, пробуренные с поверхности, которые затем используют для дегазации массива.4. The method according to claim 1, characterized in that the gasification of the underlying coal seam is carried out through vertical wells drilled from the surface, which are then used to degass the array.
