摘要
正帮煤业11104工作面上覆存在原岩庄小窑9^(#)煤采空区。鉴于常规的钻探方式探测采空区及疏排积水,存在工程量大、疏排水时间长等问题,该矿提出采用巷探代替以往的钻探方式对上覆原岩庄9^(#)煤采空区进行探查。通过巷探既能清楚收集该区域的实际地质资料,又能实现“一查全、二探清、三放净、四验准”的目标,对下一步工作面的采掘活动提供可靠的地质资料和安全保障。巷探施工方案应用后,探巷及疏排水钻孔累计排水量约2.4万m^(3),且11104工作面提前2个月贯通并回采,现场应用效果显著。
To solve the problems of large amount of work and long drainage time in the exploration of goaf and drainage of accumulated water in the 11104 working face of Zhengbang Coal Industry,the paper proposes to use entry exploration instead of traditional drilling methods to explore the goaf of overlying Yuanyanzhuang No.9 coal,which can not only clearly collect the actual geological data of the area,but also achieve the goal of"comprehensive investigation,clear exploration,clean discharge,and accurate verification",providing reliable geological data and safety guarantee for the next mining activities of the working face.The results of the entry exploration construction show that the cumulative drainage volume of the exploration and drainage boreholes is about 24000 m^(3),and the 11104 working face is completed and mined 2 months in advance,with significant on-site application effects.
