Drone airborne transient electromagnetic system and its application in the goafs of coal

The drone airborne transient electromagnetic (TEM) system independently developed by the laboratory was introduced in this paper. The system is applied to the detection of hidden water cut goaf in the coalfield of Xinjiang. Combined with the comparative analysis of known data, the accuracy and effectiveness of the detection results of the drone transient electromagnetic method are verified. The research content shows that the drone airborne TEM method is an efficient and green airborne electromagnetic new technology, and has a wide application prospect in the fine detection of geological disasters such as covert disaster control.
