Abstract: The yangguanzhai exploration area is rich in coal resources, fracture and fold structure is developed on the basis of survey data, combined with regional geological background of the exploration area were analyzed and discussed the tectonic origin. Research shows that: the yangguanzhai exploration area is controlled by the NE trending anticline in early to mid NW extrusion forming structure, controlled by EW trending extrusion forming near SN trending fault, the latter by NEE to form NWW tectonic extension. Tectonic origin is Yanshan city early synsedimentary faults, structures in the area in the North West trending, tectonic stress as early anti spin clockwise extrusion, extrusion and extension period, tectonic structural superimposed on the early due to influences of structures on NW, the occurrence of coal is larger.
