Abstract: With the geological structure of Yuanzhuang mine located in the north of Zhahe syncline in the middle segment of Xusu arc structure as the main research objects, based on the formation mechanism of various structures, this paper discussed the influence of Xusu arc structure in Zhahe syncline and Yuanzhuang mine,and analyzed the control on coal seam, methane and magmatic rocks. The research shows that though Zhahe syncline lies in abutment area in Xusu arc structure background, the folds are developed and thrust faults are less because the Carboniferous and Permian strata are soft. This phenomenon forms a sharp contrast with the thrust fault system which distributes in both sides of syncline. The structure of Yuanzhuang mine inherited the characteristics of Zhahe syncline structure and its main structure form is fold. The mining geological conditions such as coal seam, methane content and magmatic rocks are influenced by various structures obviously. The structures of different scale have certain similarity, but each also has its characteristics. Accordingly, in the research of structure of different levels not only the regional tectonic background should be considered, but also attention should paid to the study of secondary structure.
