Abstract:
Aiming at specific occurrence condition of high gas and super close distance coal seam group in Pingmei shares No.6 coal mine,in the design process of automation working face,taking coal and gas simultaneous extraction theory as the instruction,on the basis of scientifically analyzing working face gas emission law in the process of super close distance coal seam group recovery,comprehensive differentiating source gas drainage scheme of buried pipe gas drainage in upper corner and high level drilling field gas drainage are applied.On the basis of effectively controlling working face gas drainage,coal and gas simultaneous extraction technology is further optimized,which makes very obvious technical effect.
