| 摘 要： | 盘南响水井田播土采区内北西向断层成组出现，倾向相对，地面大致平行或呈透镜状延伸，深部相交消失，空间形态组合类似船体形状。通过对船形构造内的断层组合及成因分析，认为该船形构造属挽近地质历史时期形成的重力滑动构造，其两侧利用和追踪了先期形成的北西向断层，主滑面主要沿煤系地层中部的17、19煤层等软弱层发育。根据船形构造发育特点，分析了各个船形构造对煤系地层及煤层的切割破坏程度，为矿井生产中的构造预测提供了依据。

| Abstract: | There are bunches of NW faults come forth in Botu winning district, Xiangshui minefield, Pannan, their dips are visa vis, expressions on ground surface approximately parallel or lens-like extending, cut in depth mutually and fade away, their spatial configurations are similar to boat shape. Through fault combination and contributing factor analyses, considered that the boat-shaped structures are gravitational gliding structures formed in recent geologic time, borrowed and traced earlier stage formed NW faults on both sides, principal sliding faces developed mainly along the Nos.17 and 19 coal seams＇ weak zones in middle of coal measures. Based on the boat-shaped structure developing characters, cutting and disrupting extent of each boat-shaped structure to coal measures strata and coal seams analyzed, consequently provided basis for structure prediction during coalmine production. |
