Abstract

Mined-Out Area Saturated by Water is a serious threat to the safety coal-mining practices. This research focuses on detecting mined-out area saturated by water with transient electromagnetic method. Data acquisition system was arranged along 65 survey lines, and the total of 4830 survey points were recorded. An inversion technique was used to interpret the TEM data. The inversion results suggested that the mined-out areas saturated by water always exhibit a very low-resistivity, the Resistivity contour present closed circle sharp. And there are 8 mainly mined-out areas saturated by water, named JS9-1 to JS9-8 can be inferred by TEM, the interpretation result was verified by drilling, which prove the inferences of the TEM survey are excellent and that TEM is an efficient way to investigate mined-out area saturated by water.
