In order to protect the lives and property of mine workers, the influence of rocks materials slope induced by coal mining was presented. Based on geological data, a case of the mining areas of Fengmaoding anti-dip slope in China was studied using simulation analysis methods. Results show that deformation and fracture of this slope was influenced by mining subsidence, and the rock and soil layer made subsidence deformation in the vertical direction under geostatic pressure. After the deformation became stability, it would make failure strain in the horizontal direction. If initial stress of the slap’s failure in surface exceeded the shear resistance,the slope gradually slipped down, and the landslides occurred finally.
