摘要
古汉山矿16采区原始瓦斯含量高、 压力大且透气性差, 穿层钻孔抽采效果不佳, 迫切需要一种行之有效的增透抽采技术.本文结合矿井在瓦斯抽采方面存在的问题, 就高压水力冲孔造穴增透技术在1604底抽巷的应用展开分析, 以促进抽采效果的提高.
The original Guhannshan mine 16 mining area of high gas content and high pressure and poor ventilation, borehole drainage effect is poor, there is an urgent need for a effective antireflection extraction technology. Combined with the problems existing in mine gas drainage, this paper analyzed the application of high pressure hydraulic punching hole production technology in the 16041 working face, so as to improve the effect of drainage.
