摘　　要：针对高瓦斯突出矿井煤巷掘进速度缓慢的问题,提出普通钻孔与水力冲孔钻孔协同交叉布置的网络化高效抽采技术。该技术能够有效破除普通钻孔的"瓶颈效应",实现煤体整体均匀卸压,提高瓦斯抽采效率。在平顶山天安煤业股份有限公司八矿己15-14140机巷底抽巷开展了现场试验,验证了网络化高效抽采技术对煤巷掘进的效果。In view of the question phenomenon of the roadway driving low speed in high gas and outburst mines,the network-efficient gas drainage technology which is supported by conventional boreholes and hydraulic flushing boreholes is proposed. This technology could effectively remove the'bottleneck effect' around the borehoe,releasse the stress on the coal and improve the gas drainage rate. Field experiments were performed in Pingdingshan Tian′ an coal mining Co., Ltd., eighth mine sixth15-14140 bottom roadway and the effect of the technology to coal roadway excavation was verified.
