| 摘 要： | 涟邵煤田北段西部逆冲推覆构造和重力滑动构造并存,前者表现为逆冲叠瓦扇,其主干断层向下收敛于加里东不整合面附近,总体沿加里东不整合面向西逆冲推覆,后者则表现为滑片型,总体向东滑动。滑脱构造对煤层结构和煤厚变化具有明显的影响,它使煤层原生结构遭受破坏形成各种构造煤,并导致煤层厚度重新分配,形成NE—NNE向展布的厚、薄煤带。

| Abstract: | The western north sector of Lianshao coalfield has both thrusting nappe structure and gravitation gliding tectonics.The former appears as thrusting imbricated fans,the trunk fault was converged downward near the Caledonian surface of unconformity,and along this surface thrusting napped westward in the mass.The later appears as slip sheets,gliding eastward as a whole.Above mentioned decollement structure has obvious impact to coal seam structure and coal thickness,destructed primary textures of coal seams and formed different forms of coal tectonite,and redistributed coal seam thickness,a NE-NEE oriented thick and thin alternative zone thus formed. |
