摘　　要：介绍了地面瞬变电磁勘探技术(TEM)的基本原理。结合该技术对低阻体敏感、受体积效应影响小、纵横向分辨率高、施工灵活轻便且工作效率高的特点,将该勘探技术用于查明河南某煤矿勘探区内的断层带富水性,煤层顶底板主要含水层的富水性以及工区内的采空区以及老窑积水的积水情况。实际工作表明,瞬变电磁法对查明上述异常区的位置、分布范围和积水情况效果明显,为后期的煤矿安全生产提供了保障。The paper introduces the basic principles of the ground transient electromagnetic method （TEM）. In addition, we take this method to identify the water content of the fault zone and the top layer of coal seam, and water situation of the goal and the old kiln. Moreover, the actual work also shows that the transient electromagnetic method can be used to find out the abnormal area in location, distribution and water effect. Due to its advantages such as the low resistivity body, the small volume effect, high vertical and horizontal resolution, flexible, lightweight and high efficiency, TEM can provide safeguard for the safety production in coal mine.
