提前探明工作面顶板水体发育位置,能有效预防水害事故的发生。运用矿井瞬变电磁法对主采煤层顶板进行探测,沿风巷和机巷各采集一组数据。经解译结果对比分析,风巷、机巷探测的低阻异常区位置基本一致,其位置略向风巷一侧偏移,在回采过程中应予以重视。
It is necessary to ascertain the development position of roof water body in advance, which can effectively prevent the occurrence of water hazard accident. Using the mine transient electromagnetic method to detect the roof of the main seam, collect a set of data along the wind lane and machine lane respectively. After comparative analysis of the interpretation results, the location of the low resistance anomalous zone in wind tunnel and machine lane exploration is basically the same, the position of the low resistance anomalous zone is slightly shifted to the side of the wind lane, and should be taken seriously in the process of recovery.
