Abstract Fault structure destroys coal measures strata and reduces the reserves of coal resources. Coal mining face passes through faults, which increases the cost of coal mining and brings the risk of water outburst and gas accumulation. It is necessary to carry out concealed fault structure detection in coal mining face. At present, the main geophysical methods of coal mining face are seismic wave method and electromagnetic method. As a fine geological detection method, ground penetrating radar technology can play an important role in the detection of hidden fault structures. In this paper, the types and causes of faults were analyzed according to the geological characteristics of Huayang No.1 Mine. The finite time domain difference method was used to simulate the ground penetrating radar detection data of different strike fault structures. The data characteristics of different structures were analyzed, and a fault strike inference method based on electromagnetic wave reflection path was proposed. The concealed fault structure in the mining area was detected by 100 MHz ground penetrating radar. The detection results showed that the strike and range of the fault structure in the mining area could be estimated by combining the amplitude of the target reflected wave and the change of the horizon. Combined with the revealed dip angle, drop and other information, it provided a basis for pre-adjusting the mining face.

Key words： geological detection fault structure ground penetrating radar data processing
