Claims (1)

Способ подземной газификации угля, заключающийся во вскрытии угольного пласта буровыми скважинами, последующем розжиге газогенератора и его осушении, выгазовывании угольного пласта путем подачи дутья через одни скважины и отвода образовавшегося газа через другие скважины, а также контроле за основными технологическими и гидрогеологическими параметрами и их регулировании, отличающийся тем, что периодически измеряют уровень столба подземных вод на участке газификации и давление в подземном газогенераторе, регулируют степень открытия задвижек на газоотводящих скважинах и уровень воды в водопонижающих скважинах, а также поддерживают отношение давления в подземном газогенераторе к давлению столба подземных вод 0,75 - 1,0.The method of underground gasification of coal, which consists in opening the coal seam with boreholes, then firing the gas generator and draining it, gasing the coal seam by supplying blast through one well and venting the formed gas through other wells, as well as monitoring the main technological and hydrogeological parameters and their regulation, characterized in that periodically measure the level of the column of groundwater in the gasification section and the pressure in the underground gas generator, regulate the degree of opening valves for hot gas wells and the water level in the dewatering wells, and the pressure ratio is maintained in the subterranean gasifier pressure groundwater post 0.75 - 1.0.
