摘要
为提高瓦斯抽放钻孔抽放效率,降低瓦斯抽放钻孔施工工程量,延长钻孔抽放时间,加大钻孔抽放范围,研究分析3#软岩煤层N1206运巷掘进期间传统瓦斯抽放钻孔布置及存在问题,决定利用ZDY-6000LD(F)型千米钻机在软岩煤层中钻孔抽放瓦斯,实际应用取得了显著成效。
In order to improve the efficiency of gas drainage borehole drainage, reduce the gas drainage borehole construction quantity, prolong drilling drainage, increase drilling drainage, the traditional layout and existing problems of gas drainage boreholes during the driving of N1206 transport roadway in No. 3 soft rock seam were studied and analyzed. It was decided to use ZDY-6000LD(F) type kilometer drilling machine to drill gas drainage in soft rock seam, and remarkable achievements were achieved in practical application.
