Abstract：According to the deformation situation of Baorixile Open-pit Mine south slope, the mine carries out presser foot treatment of slope. The 3D numerical analysis model is established according to the presser foot parameters of the internal dump and the mining parameters of the coal seam. The article simulates and analyzes the deformation and failure laws of the southern end slope under different internal dump tracking distance, and studies the change regulation of stress and displacement of the south side slope during the advancing of the work face, and determines the reasonable tracking distance of internal dump, which has an important guiding significance for the production practice of this mine
