摘要
隐伏断层作为良好的导水通道,一直是煤层顶板突水的潜在威胁,威胁矿井安全生产,因此迫切需要物探手段查明隐伏断层的性质、落差、产状、富导水等情况,指导煤矿防治水工作。以古城煤矿勘探资料为例,通过三维地震、瞬变电磁两种勘探手段,在分析勘探区地球物理特征的基础上,对隐伏断层的地震和电性响应特征进行综合分析,最终查明隐伏断层的构造特征及其导水性。
Hidden faults, as good water channels, have alwaysbeen a potential threat to safety production caused by water inrushfrom coal seam roof. Therefore, there is an urgent need for geo-physical methods to identify the nature, drop, attitude, and richconductivity of hidden faults, in order to guide coal mine water pre-vention and control work. This article takes the exploration data ofGucheng Coal Mine as an example, and uses two exploration meth-ods:3D seismic and transient electromagnetic. Based on the analy-sis of the geophysical characteristics of the exploration area,thescismic and electrical response characteristics of hidden faults arecomprehensively analyzed. Finally, the structuralcharacteristicsand water conductivity of hidden faults are identified.
