摘要
结合矿井工作面生产实际,对运用坑透探测法、震波CT探测法、底板三维电法对8#煤工作面陷落柱的边界范围及其富水性等情况进行探测的结果进行了分析。工程实践表明,该次探测结果与实际陷落柱范围基本吻合,属于不富水陷落柱,本次探测结果对本工作面安全回采和下层煤开采设计具有重要指导意义。
Combined with the actual production at the working face of mines, this paper analyzed the detecting results of the boundary range and water rich of the collapsed column of 8#coal mining face by using pit penetration method, seismic wave CT detection method and floor three-dimensional electric method. The engineering practice showed that the results were basically consistent with the actual range of the collapsed column, which was non-rich water collapsed column. The results of this survey had important guiding significance for the safe backstopping of the working face and the design of the lower coal mining.
