摘要
The transient electromagnetic method can accurately determine coal mined-out area and mined-out area with water. A certain coal mined-out area and mined-out area with water was determined by this method in this paper. Firstly, the authors make sure resistivities of coal mine wall rocks through the contrast of apparent resistivity curves ρτ and columnar diagram of drilling holes, and established theory model for anomaly interpretation. According to the measured data of the transient electromagnetism, combining with characteristics of coal measure strata, the authors determined coal mined-out area and mined-out area with water.
