煤矿巷道超前综合物探方法在平朔矿区的应用

Application of Advanced Comprehensive Geophysical Prospecting Method about Coal Mine Roadway in Pingshuo Mining Area

针对常规钻探不能全面掌握回采巷道附近地质构造和老空区分布情况的不足,平朔矿区进行了巷道超前综合物探方法试验,分别采用地震映像探测法、TSP超前预报法、双频激电超前预报等方法对4109主、辅巷各位置进行了综合探测。通过分析,初步探明了4109主、辅巷道周围地质构造和老空区分布状况,对指导具体开采活动具有重要意义。

For geologic structure near mining roadway and goaf distribution are not comprehensively grasped by conventional misering. The experiment of the roadway advanced comprehensive geophysical prospecting method is conducted in Pingshuo mining area,and the methods such as seismic imaging detection,TSP advanced prediction, dual frequency IP advanced prediction and others are adopted respectively to detect the position of 4109 face main and auxiliary roadway. Geologic structure around 4109 face main and auxiliary roadway and distribution state of goaf are detected preliminarily by analyzing. It has a significant for directing specific mining activity.
