摘　　要：为了防治煤矿水害,应用矿井瞬变电磁法探测巷道掘进前方及工作面顶、底板的富水异常区,巷道环境的不同对观测曲线有一定的影响,对其进行校正,提高矿井瞬变电磁的解释精度,从而有效开展煤矿防治水工作。To control coal mine water disasters,by using mine transient electromagnetic method,water-rich area was detected in the ad- vance of roadway driving and the roof and floor of working face. Different environments of roadway have a certain influence on observation curve, relevant correction was carried out to improve the interpretation accuracy of transient electromagnetic method, so the water prevention and control project can be carried out effectively.
