Description
Известны способы дегазации пластов каменного угл , осуществл емые путем отсоса газа через дренажные скважины, проведенные в плоскости дегазируемого пласта, не разгруженного от горного давлени , а также путем отсоса газа через дренажные скважины, проведенные по межпластовым породам перпендикул рно к дегазируемому пласту, разгруженному от горного давлени .There are known methods for degassing rock coal seams carried out by suctioning gas through drainage wells held in the plane of a degassed formation not unloaded from rock pressure, and also by sucking gas through drainage wells conducted across interlayer rocks perpendicular to the degassed formation unloaded from a mountain pressure.
Особенностью предлагаемого способа вл етс ведение процесса дегазации в услови х сочетани разгрузки дегазируемого пласта от горного давлени путем выемки нижележащего пласта с отсосом газа через коллекторы, наход щиес в плоскости дегазируемого пласта.A feature of the proposed method is the management of the degassing process under the conditions of combining the discharge of a degassed formation from rock pressure by excavating the underlying formation with suction of gas through reservoirs located in the plane of the degassed formation.
В результате проведени этого меропри ти получаетс увеличение степени дегазации пласта с повыщением концентрации извлекаемого газа.As a result of this measure, an increase in the degree of degassing of the reservoir is obtained with an increase in the concentration of recoverable gas.
Осуществление описываемого способа по сн етс схемой (см. чертеж).The implementation of the described method is illustrated by the scheme (see drawing).
Предмет изобретени Subject invention
Способ предварительного извлечени газа при подземной разработке горючих ископаемых, отличающийс тем, что газ отсасывают непосредственно из пласта полезного ископаемого, разгруженного от горного давлени путем выемки нижележащего пласта.A method of gas pre-extraction in underground mining of combustible minerals, characterized in that the gas is sucked off directly from the mineral formation unloaded from rock pressure by excavating the underlying formation.
