| Abstract: | This paper introduced the principle, technology, method and application of transient electromagnetic method in mine roadway leading prospecting. Then it discussed the effectiveness of mine TEM technology in detecting gob water ahead of the tunneling. It concluded several.key issues which require notice in the application of mine TEM. Proved by an example,TEM is an effective way for the request of mine roadway leading prospecting. In an example, the spatial feature of anomaly body can be reflected exactly using the TEM in advanced detection, thus it provides a foundation for mine water control. |
