摘　　要：隐伏地质构造的超前预报是预防煤矿突水事故的关键。为查明龙岩市大弯煤矿+10巷道迎头前方构造的发育分布状况及富水性,在分析断层构造的弹性、电性等地球物理特征前提下,结合井下巷道现场实际生产环境,采用震波超前探和瞬变电磁法对+10巷道前方导水地质构造实施综合探测和分析。结果表明:地震与瞬变电磁综合物探方法较单一方法具有较大的成果解释精度优势,其现场观测可充分利用先实施的震波超前探测技术定位断层等构造位置,进而实施瞬变电磁超前探测技术予以补充验证,并根据电阻率异常判别其富水情况,能够为巷道施工和防治水措施的实施提供更准确的地质和水文地质参数。Advance forecast of concealed geological structure is the key to prevent water inrush accident in coal mine. In order to find out the water abundance and development distribution situation of water conducted structure ahead of the + 10 roadway head,based on the analysis of geophysics premise such as elasticity and the electric magnetic differences,combining with the actual production data of roadway,the seismic probing mine seismic prediction and transient electromagnetic method are used for advance detection of +10 roadway. The results show that the integrated geophysical prospecting method has better results interpretation accuracy compared to single geophysical method,in on-site observation it can make full use of the advance seismic wave detection technology to locate structural locations such as faults,and then implement transient electromagnetic advance detection technology for verification,and determine its water-rich situation according to the resistivity anomaly,which can provides more accurate geological and hydrogeological parameters for roadway construction and water prevention measures implementation.
