摘　　要：针对富康源矿复杂的顶板岩层地质条件和瓦斯赋存运移特征,开展了以孔代巷技术研究,从采动裂隙发育规律和钻孔抽采特征方面,分析了高位水平长钻孔和大直径定向钻孔替代顶板抽采巷的技术原理。通过高位水平长钻孔的施工及抽采效果,探明顶板地层详细信息,以此优化定向钻孔层位布置、钻具组合和钻进参数。抽采效果表明,该抽采模式可以在2106工作面应用,研究可为井下瓦斯高效抽采与治理提供借鉴。In view of the complex geological conditions of the roof strata and the characteristics of gas storage and migration in Fukangyuan Mine,the study on the technology of replacing the roadway with holes was carried out,and the technical principle of replacing the roof drainage roadway with high-level horizontal long boreholes and large-diameter directional boreholes was analyzed from the aspects of the development law of mining fractures and the characteristics of borehole drainage.Through the construction and pumping effect of high-level horizontal long borehole,the detailed information of roof strata is proved,so as to optimize the directional drilling horizon layout,drilling tool assembly and drilling parameters.The pumping effect shows that the pumping mode can be applied in 2106 working face,and the research can provide a reference for the efficient gas drainage and control in the underground.
