摘　　要：瞬变电磁法是目前探测富水区效果较理想的一种方法,具有分辨率高、与地质体耦合性好、对低阻地质体反应灵敏等特性,可分辨出地下规模较小的不均匀体,明显反映出富水区的低阻特性。结合实例介绍了瞬变电磁法在煤矿采空区、矿井涌水通道等富水区探测中的应用情况。Transient electromagnetic method is an ideal method in the detection of water-rich area,it has high resolution,good coupling performance to the geologic body,and can reflect the information of geological body with low resistance sensitively. It also can distin- guish the smaller heterogeneous objects, reflect the low resistivity characteristics of water-rich area apparently. The application of transi- ent electromagnetic method was introduced by using the examples of detecting water-rich areas, such as coal mine gob and the water-in- rush channels.
