| Abstract: | Transient electromagnetic method( TE M) is a branch method of electrical prospecting which has developed rapidly in recent years. It is widely used in solving geological problems such as mineral, hydrological and engineering prospecting in China, especially in the exploration of metal minerals and mined-out areas of coal mines. But there are also some problems that are easy to be neglected and affect the exploration effect. This paper explores and analyses the application of transient electromagnetic method in the goaf of a coal mine. |
