基于矿井瞬变电磁原理，分析了固定平移法、转换角度法、综合法等矿井瞬变电磁探测工作方法及其适用范围。通过实例研究了断层裂隙水、充水陷落柱、采空区积水、导水裂缝带等矿井瞬变电磁探测异常特征，结果表明：矿井瞬变电磁对各个含水异常体的反应较为明显，且呈现出不同的异常特征。通过矿区井下含水构造实地探测和井下巷道超前探测跟踪试验，研究了瞬变电磁探测的准确率，统计得出矿井瞬变电磁整体探测成功率约为86．2%，是井下比较实用的探测水害的物探方法。

Based on the mine transient electromagnetic theory, analysis was made on the working method and application scope of the mine transient electromagnetic detection including the fixed translation method, conversing angle method and comprehensive method. Through the cases, study was carried out on the abnormal characteristics of the mine transient electromagnetic detection such as the fault fracture water, water-filled subsided column, gob water, water flowing fractured zone and so on, the results showed that the mine transient electromagnetic response was more obvious for each water-bearing anomaly and presented different abnormal characteristics. Through the field detection of underground water-bearing structures and the following test of the advance detection in mine roadway, study was made on the accuracy of the mine transient electromagnetic detection. The statistics indicated that the overall success rate of the mine transient electromagnetic detection was about 86. 2%, so it is a more practical geophysical method for mine flooding.
