摘　　要：彬长矿区位于陇东黄土塬区,地表条件复杂且煤层埋深较深,影响三维地震勘探法探测煤层构造(断层)的精度,平面摆动误差较大。为了弥补探测精度的不足,进一步掌握断层的发育位置,科学指导矿井巷道安全、高效的掘进,在胡家河煤矿某工作面采用槽波地震超前探技术对该工作面巷道前方断层发育情况进行探测及分析。经过数据整理、反射波提取、速度建模分析和深度偏移处理技术获得巷道迎头前方的地震反射偏移剖面。实践表明,槽波地震超前探能够对断层的位置进行准确解释,通过再次对三维地震勘探资料进行分析,大大提高了解释的精度,对三维地震勘探是一个很好的补充,也为矿方后续工作提供可靠的地质依据。Binchang mine area is located in the Loess Plateau of Longdong,the surface conditions are complicated and the coal seam is buried deep,which affects the precision of 3D seismic exploration of coal seam structure(fault),and the plane swing error is large.In order to make up for the lack of exploration accuracy,further find out the development position of the fault,and scientifically guide the safe and efficient excavation of the mine roadway,the slot wave seismic advanced exploration technology is used to detect the development of the fault in front of the roadway of the working face in Hujiahe Coal Mine.Through data processing,reflection wave extraction,velocity modeling analysis and deep deviation processing technology,the seismic reflection deviation profile in front of the roadway face is obtained.The results show that the fault location has been accurately interpreted by the slot wave seismic advanced exploration in Hujiahe mine.The interpretation accuracy has been greatly improved via analysis of the 3D seismic exploration data.The method is a good supplement to 3D seismic exploration and provides reliable geological basis for the subsequent work of the mining area.
