摘　　要：南水北调中线一期工程总干渠禹州矿区段存在线路比选问题,无论是隧洞方案还是绕线明渠方案都不可避免穿过煤矿采空区,严重威胁着工程建设安全。由于存在煤矿开采系统不正规、地质资料及采煤资料匮乏等问题,采空区探测一直是业内的技术难题。工程物探方法具有探测深度大、分辨率高及工作效率高的优点,是进行煤矿采空区探测的主要手段。文章综合运用瞬变电磁法和地震勘探法对沿线的煤矿采空区进行了探测,取得了较好的应用效果,基本查明了两种比选方案渠道沿线采空区的分布情况,为渠道线路的优化设计提供了依据,为后期施工建设及保障工程安全提供强有力的技术支持。There is a problem of route comparison and selection in Yuzhou mining area section of the main canal of the Middle Route Project of South-to-North Water Diversion.Both the tunnel scheme and the winding open channel scheme inevitably pass through the goaf of coal mine,which seriously threatens the safety of engineering construction.Due to the problems of irregular coal mining system,lack of geological data and coal mining data,goaf detection has always been a technical problem in the industry.The engineering geophysical method has the advantages of large detection depth,high resolution and high work efficiency,which is the main means of coal mine goaf detection.In this paper,the transient electromagnetic method and seismic exploration method are used to detect the coal mine goaf along the line,and good application results are obtained.The distribution of goaf along the channel is basically found out in the two comparison schemes,which provides the basis for the optimal design of the channel route and provides strong technical support for the later construction and the guarantee of project safety.
