Abstract

The slope of the west working side of the south mining area of the open-pit coal mine where a landslide has occurred is taken as the research object. The paper selects Mohr-Coulomb elastoplastic model to analyze the slope stability of the western working side of the southern mining area of the open-pit coal mine by Finite Element Method. The numerical simulation results show that the rear edge of the sliding slope area is still in an unstable state and the front landslide mass is still in a creep state, and the local step plastic zone of the slope body is penetrated. On the basis of this, slope safeguard measures of slope cutting, backfilling and Drainage engineering to protect the slope stability are put forward. The research results provide a theoretical basis for the treatment of deformation and failure of similar slopes.
