The relationship between Panji anticline and the development characteristics of interlayer-gliding structure in Panji mine

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.
