Abstract:
In order to optimize the detection effect of geological anomaly body in high outburst mine, based on seismic method and radio wave perspective technology, combined with gas geological factors of high outburst mine, the portable seismic method, which takes hammer excitation as the source and rolling short array detection as the measurement method, combined with the high-density radio wave perspective method, is used to carry out the differential detection of key and difficult areas. An efficient and precise comprehensive detection technique for geological anomalies is proposed. The results show that this technique can be used to detect the distribution of fine geological anomalies such as faults and fissures within 100 m of the working face and its periphery. It can eliminate the hidden danger brought by blasting construction of geophysical prospecting to the high outburst mine, and perfect the geological structure distribution information of the coal strata inside and around the working face. At the same time, the contrast detection of heavy and difficult areas can improve the efficiency of geophysical exploration and realize the efficient and fine detection of geological anomalies in high outburst mines.
