Abstract This paper details with topography, surface water and geology of the study area. The results provide a basis for the choice of detection methods. Based on electrical property of the detection area, the authors hold that TEM is well suitable for the study of the detection area. The authors compared and analyzed the parameters of resistivity and found that the stratigraphic physical character differences could effectively determine the distribution of water log in goaf and collapses columns, thus guaranteeing safe production.
