Abstract:
The structural characteristics of Panji anticline and tectonic stress field in Panji coal mine were studied and Panji mining area is divided into 10 main interlayer-gliding areas and 29 sub-areas by analyzing the features and types of the interlayer-gliding structures. The results indicate that the direction of the interlayer-gliding structures is closely related to the direction of N-S principal stress field and the local stress field formed by the large-scale fault structures. The EW trending thin seam zones and the type, Ⅱ Ⅲ tectonic coal were caused by the interlayer-gliding. The interlayer-gliding structures mainly developed in the anticline wings, with fault-sliding and corrugation as dominant structures in the wings, fracture in the core of anticline. Vertically, the types of the interlayer-gliding structures have obvious regularities. In the relatively shallow area, interlayer sliding structures are mainly fractures, downward are fault-sliding type and corrugation type is mainly developed in the deep part or the interchange of the faults.
