| 摘 要： | 通过淮南煤田张集井田层滑构造的具体表现形式分析,对层滑构造进行了系统分类。根据层滑构造的表现形态分为揉皱型和断裂型两种基本类型,根据不同层滑构造的组合形态又可分为书斜式、垒堑式、阶梯状和"y"与反"y"字形等,并采用物理模拟方法对不同层滑构造类型进行了实验研究。运用镜质体的反射率各向异性恢复了矿区构造应力场,张集井田中生代以来至少受到两期构造应力场作用,NWW-SEE方向的拉伸是形成张集井田层滑构造的主要力学机制。 |

| Abstract: | By analyzing features of numerous structures in the Zhangji Coalmine, Huainan area, the interlayer-gliding structures are classified into two basic types: the corrugation type and fracture type. According to the assemblages of the two types of interlayer-gliding structures, they can be further subdivided into domino-style, graben-and-horst, step-fault, "y" and "anti-y" structures. Experimental modeling is employed to investigate the mechanism(s) of the different types of interlayer-gliding structures. The vitrinite reflectance anisotropy data revealed at least two stages of tectonic stress since Mesozoic in the Zhangji Coalmine. The experimental modeling indicates that the NWW-SEE direction extensional stress was probably the main dynamic factor controlling the geometry of the interlayer-gliding structures in the Zhangji Coalmine. |
