For the seismic exploration,with the depth of deep coal resources to increase the depth of the ground seismic resolution significantly reduced and imaging difficulties,difficult to meet the geological needs of efficient and safe mining,how to carry out coal seam hidden structure The detection becomes an urgent need to solve the problem.The existence of these practical technical problems,forcing people to look to the coal mine seismic exploration technology research.Based on consulting the coal mine seismic exploration technology at home and abroad in recent 10 years,on the basis of related literature,comprehensively discusses the research status of the coal mine seismic exploration technology,leveling shares mine working face as the research object,analyzed emphatically in the complex geological conditions in the process of production,such as fault,fracture zone and unstable coal seam geological anomaly exists.The use of slot-wave seismic exploration technology to achieve accurate detection and timely prevention.Firstly,a typical geophysical model of coal.bearing strata in the research area is established to study the response characteristics of the trough wave field under different geological conditions,so as to select the optimal parameters.Secondly,the establishment of the downhole transmission channel wave seismic exploration in the study area of the observation system,the proliferation of geometric correction,data processing technology,such as multiple filtering of collected channel wave seismic data processing and theoretical analysis.Finally,the seismic interpretation results of the channel wave are compared and verified with the geological data of the research area,and the accuracy and coincidence degree are obtained.Not only make full use of this technology has a large detection range,high precision,strong anti-interference ability,waveform character is relatively easy to identify and direct final results,and has huge development potential and good popularization value.
