综合物探在某矿3302工作面顶底板中探水的应用

Application of Comprehensive Geophysical Method in Top and Low Roof at No.3302 Coal Face

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。

For the harm seriousness of coal mine accidents harm and drilling mine advance ground water long time limit for a project,and the problem of high cost,by means of comprehensive geophysical prospecting method,roof and floor of 3302 face detection a mine of Shanxi,through the analysis of the detection results found the low resistivity anomaly area of working face. By comparing find high density resistivity method detection results largely consistent with transient electromagnetic exploration results,verify the accuracy of detection results. Using the comprehensive geophysical prospecting method prevent the flooding of the mine 3302 working face of provides a reliable technical guarantee.
