1. Способ подземной газификации угольных пластов, включающий бурение скважин с поверхности, подготовку и розжиг подземного газогенератора с отводом генераторного газа и попутной дегазацией вышележащего массива, отличающийся тем, что определяют положение первичных сводов разгрузки подрабатываемого массива подземным газогенератором, а дегазационные скважины бурят в вершины указанных сводов.1. The method of underground gasification of coal seams, including drilling wells from the surface, preparation and ignition of an underground gas generator with the removal of generator gas and associated degassing of the overlying massif, characterized in that the position of the primary arches of the discharge of the worked-out massif is underground gas generator, and degassing wells are drilled to the tops of the indicated arches. 2. Способ по п.1, отличающийся тем, что расстояние между дегазационными скважинами В определяют по формуле2. The method according to claim 1, characterized in that the distance between the degassing wells In is determined by the formula В=2(Н-Нв)·ctgΨ, м,B = 2 (Н-Н в ) · ctgΨ, m, где Н - глубина залегания газифицируемого угольного пласта, м;where H is the depth of the gasified coal seam, m; Нв - глубина залегания верхнего пласта угленосной свиты, м;N in - the depth of the upper layer of the coal-bearing suite, m; Ψ - угол полных сдвижений подрабатываемого массива, град.Ψ - the angle of complete displacements of the undermined array, deg.
