Abstract In the complex structure of the mine, the concealed geological body is the main factor restricting the safe production of the mine. How to accurately and efficiently identify the concealed geological abnormal body is a problem which must be solved in the construction of intelligent and transparent mines. Taking No.5-302 Face of Jinbei Coal Industry as an example, this paper used in-seam wave seism exploration technology to detect the concealed geological structure in the working face. Through dispersion analysis, spectrum analysis, energy analysis and other channel wave seismic data processing methods, the distribution of concealed geological structures and other abnormal bodies in the working face could be found out, which had certain reference and guiding significance for the detection of mining face in mines with complex structures of the same type.
