摘　　要：层间距较小的上部采空区积水是影响下组煤安全回采的重要因素,不疏放上部采空区积水,将会对未来的工作面回采造成重大隐患,但又不能盲目布置钻孔进行疏放,因此对上部采空区积水范围的探查将会对下一步的疏放水产生重要意义。本文通过对地面与矿井物探、多种矿井物探方法的对比分析后,采用矿井瞬变电磁法和无线电波透视法相结合的综合物探手段对上部采空区积水进行了探查工作。研究结果表明,通过现场数据采集、数据处理、资料解释和综合分析,可以圈定上覆采空区的积水区域,从而为疏放水钻孔的布置提供良好的地质依据,证明了选择方法的准确性和有效性。The ponding in the upper goaf with small layer spacing is an important factor affecting the safe recovery of the lower group of coal,not releasing the ponding in the upper goaf will cause significant hidden danger to the future workings recovery,but cannot blindly arrange drilling holes for releasing.Therefore,the exploration of the extent of ponding in the upper goaf will be of great importance to the next step of water release.In this paper,a combination of mine transient electromagnetic method and radio wave penetration method are used to explore the water accumulation in the upper goaf after a comparative analysis of surface and mine physical surveys and multiple mine physical survey methods.The research results show that through field data collection,data processing,data interpretation and comprehensive analysis,the ponding in the overlying goaf can be circled,thus providing a good geological basis for the placement of water release boreholes and proving the accuracy and effectiveness of the selected method.
