Mine geological structure is an important geological factor that affects coal mine safety production. Based on detailed underground geological observations and surface geological survey data, starting with the study of structural traces and structural stress field, the Lubanshan mine field’s geological structural characteristics and structural stress field distribution are analyzed. The research results show that the structural profile of the Lubanshan mine field is mainly controlled by the NE-directed Xunsi anticline. The geological structure at the edge of the minefield is more complicated and the internal geological structure is relatively simple. The development of small faults and layer-slip faults, often in groups of coal seams or coal seam roof and floor, has become one of the biggest obstacles restricting coal mine safety production.
