Abstract：The application of comprehensive geophysical methods to the detection of mined-out areas can fully take advantage of multi-information and can also eliminate the technical limitation of a single method so that the goal of effective detection of mined-out areas can be achieved. In this paper, with a coal mine in Yunnan Province as a study case, the authors applied seismic method, high-density DC method and transient electromagnetic method (TEM) to conducting comprehensive geophysical prospecting. Based on the combined analysis of the geophysical response of seismic field, DC field and electromagnetic field, the authors successfully detected the range of the mined-out area in the prospecting district, with the exploration results verified by drilling.
