摘　　要：为掌握3506综采工作面内地质构造分布情况,将槽波地震探测技术应用于采面构造探测中,综合使用槽波反射法以及槽波透射法进行探测,并依据现场情况确定测点布置。在采面回采巷道及切眼内间隔10 m布置检波点、间隔20 m布置激发点。对探测得到的数据进行解释分析,发现开采范围内存在有4条落差均超过煤层厚度的断层,并确定断层分布位置、延展方向等,后续3506综采工作面回采时均揭露槽波地震断层且位置偏差在10~20 m以内,表明探测结果可靠,可指导采面生产。In order to master the distribution of tectonics in 3506 fully mechanized mining face,the trough wave seismic detection technology is applied to the detection of mining face structure,and the trough wave reflection method and trough wave transmission method are comprehensively used for detection,and the layout of measuring points is determined according to the site conditions.Arrange detection points at an interval of 10 meters and excitation points at an interval of 20 meters in the mining roadway and cutting hole of the mining face.Interpreting and analyzing the data obtained from the exploration,it was found that there are four faults within the mining area with a drop exceeding the thickness of the coal seam,and the distribution position and extension direction of the faults were determined.Subsequently,during the recovery of the 3506 fully mechanized mining face,slot wave seismic faults were exposed with a positional deviation of 10~20 meters,indicating that the detection results are reliable and can guide the production of the mining face.
