Coal mine underground roadway transient electromagnetic stack advanced detection device and method

The present invention belongs to the coal mining geophysical prospecting technical field, relates to a transient electromagnetic stack advanced detection device and method, in particular, a coal mine underground roadway transient electromagnetic stack advanced detection device and method. According to the device and method of the invention, a probe is arranged in a borehole, so that the probe can be far away from interference sources such as metal machineries in a roadway, and therefore, the influence of the interference sources can be avoided; the hole drilling conditions of a coal mine tunneling face are fully utilized, so that inside-roadway coil emission and inside-borehole three-component receiving can be realized; and a receiving device can move towards a direction before the tunneling face, and therefore, various kinds of the interference of the metal machineries at the tunneling face can be avoided without affecting the tunneling work of a mine party, and the advanced detection data of a plurality of positions in the borehole can be subjected to stack processing, and processing results can be displayed, and thus, hidden water damage geological bodies before the tunneling face can be predicted at an extra long distance.
