通过对湘中坳陷托山煤矿进行野外地质调查、地质构造研究及矿井内巷道的小断层分析，探讨了逆冲、滑脱构造的特征、形成机理和演化过程。研究结果表明：托山矿区下石炭统测水煤系5煤层具备发育顺层构造的物质条件，属托山煤矿推覆构造潜在主滑面，矿区重力滑覆与挤压推覆并存。滑覆和推覆构造形成于不同时期、不同构造环境中，具有各自的组合形态及演化历史。构造反演显示托山矿区的滑脱构造历经早期逆掩、中期逆冲、晚期反向重力滑脱转型3个不同阶段。

By field geological survey and geological structure study and small fault of the mine roadway analysis,the characteristics,formation mechanism and evolution process were probed into,which of overthrust and decollment structures in Tuoshan coalfield of Xiangzhong depression.The study results show that Ceshui 5 coal in Tuoshan,the lower carboniferous has dynamics condition of well -development bedding structure,and it is the nappe main potential sliding surface of Tuoshan coalfield.The mining area exist gravity sliding cover as well as squeeze the nappe.Sliding cover and nappe structure formed in different periods and different tectonic environment,combined with their own form,and evolution history.The tectonic inversion shows detachment structures in this area has experienced three difference stages:overthrust in the early stage,thrust strengthen in the middle stage,reverse gravity sliding in the late stage.
