Method for degassing gas-coal beds includes well drilling to section of rock massif being degassed, sealing of productive section of well, extraction of coal seam with production face, suction of gas from the well. In addition one performs measurement of deformation of rock massif and sets parameters of zone of local unloading of massif before production face. Force effect on productive sections of well one performs in period of its presence in zone of local unloading. |
