| Abstract: | Through the implementation of ＂ doing the drill field, jet grouting, strong growth through＂ nine - character principle and the fine drainage requirements of ＂drill in right place, the tube in the end, the hole seals fully, water put through＂, pre -extraction of strip perforating layer drilling were carried out in the floor to realizing eliminate sudden fully. The cancel of partial measures hole construction of coal roadway can improve the driving efficiency and achieve maximized gas extraction and utilization. |

| Keywords: | pre - extraction of strip perforating layer drilling gas drainage and utilization maximization |
