摘　　要：煤矿积水采空区由于其复杂性,在进行瞬变电磁法探测时,常常会产生一些附加效应。从理论、试验出发,研究了附加效应的特点及探测曲线特征,并根据这些特点对实际工程进行了分析、解释,圈定的积水采空区经钻探验证,效果良好。Mined-out area with accumulated water in coal mines is difficult to detect because of its complexity. In TEM detection, there are often additional effects, the paper, from the theory and test, studied the effect of the additional features and detecting characteristics of the curve, and on the basis of these characteristics, the actual engineering analysis and interpretation were carried out, drilling verified that mined-out area with water was well localized.
