针对平岗煤矿1202综采面本煤层透气性低、瓦斯含量大、本层钻孔抽采效果不佳的情况,通过采用本煤层高压注水的方法,使本层瓦斯抽采量成倍提升,解决了煤层透气性差,无法有效抽采本煤层瓦斯的问题。
In view of the low gas permeability and large gas content in the 1202 fully mechanized mining face of Pinggang Coal Mine, the gas drainage in this coal seam is doubled by adopting the method of high pressure water injection in this coal seam. It solves the problem of poor gas permeability of the coal seam and the inability to effectively pump the gas of the coal seam.
