Abstract: To analyze the influence mechanism of crushing station load on slope stability, clarify the deformation and failure characteristics of slopes under different load distributions, and ensure safe mining. This paper proposes an expression for the slope safety factor under the influence of uniformly distributed loads at the top of the slope based on the limit equilibrium method, and reveals the mechanism of the influence of crushing station loads on slope stability. And numerical calculation models of slopes with different load distributions are established. The results show that the displacement of the slope facing the free face decreases with the increase of the safety distance. When the safety distance is less than 10 m, the safety distance of the load action is less than or equal to the projection length of the inclined surface of the sliding block at the horizontal plane. The slope is greatly affected by the load of the crushing station, and there is a clear tensile yield zone distributed at the rear edge of the sliding block. The failure mode is “shear tensile fracture failure”, manifested as a “sitting pushing” sliding mode. When the safe distance is greater than 10 m, the trailing edge of the sliding body is no longer affected by external loads, and the angle between the displacement direction of the rock mass and the horizontal plane under the action of the crushing station decreases, showing obvious shear failure characteristics. The sliding mode also changes to a “circular arc” shape, manifested as a “circular arc” overall sliding mode. The slope safety and stability factor is almost not affected by the load of the crushing station and meets the safety requirements of the mine.
