摘　　要：一缘煤业在150112运输巷进行了水力割缝增透预抽瓦斯试验,结果表明:相同长度的水力割缝钻孔(11个)相对于普通钻孔(12个)平均日总抽采量从715 m^3提高到2 674 m^3,瓦斯抽采效果显著提高,保证了掘进的安全。A coal industry carried out a hydraulic slit penetration pre-pumping gas test in the 150112 transport lane.The results show that the average total daily extraction volume of hydraulic slit drilling(11)rrelativing ordinary drilling(12)of the same length has increased from 715 m^3 to 2 674 m^3,and the gas extraction efficiency has improved significantly,thus ensuring the safety of excavation.
