针对煤矿透水事故危害的严重性及矿井超前钻探探水存在工期长且成本高的问题,通过采用综合物探法对山西某矿3302工作面顶底板进行探测。通过对探测结果的分析发现该工作面的的低阻异常区域,通过比较得出高密度电法探测结果与瞬变电磁探测结果大体一致,验证了探测结果的准确性。采用综合物探法,为预防该矿3302工作面透水事故提供了可靠的技术保障。
In view of the seriousness of coal mine flooding accident hazard and long time and high cost of advanced drilling water exploration in the mine, the roof and floor of 3302 working face of a mine in Shanxi were probed by using the comprehensive geophysical exploration method. Through the analysis of the detection results, it is found that the low resistivity anomaly area of the working face is in agreement with the transient electromagnetic detection results obtained by comparison of the high density electrical detection results, and the accuracy of the detection results is verified. The use of integrated geophysical methods provides a reliable technical guarantee for preventing seepage accidents in the 3302 face of the mine.
