  • The impact of collapse or colluvial gravitational load may induce deformation and instability of landslide. On the basis of ascertaining slope structure,this paper applies the 3DEC discrete element numerical simulation method to simulating the mechanism,the scale of buckling mode,destruction and movement by the collapse of high and steep slope under the action of underground mining overall process. It especially analyzes deeply the interaction effect of slope after instability and landslide. The results show that the process of collapse by underground mining can disturb the underground mining slope and can produce a massive collapse. The rolling stones by collapse can have a strong impact on landslide. The generated colluvial deposits can have a gravitational load on landslide. The creep deformation of landside is mainly caused by the impact of colluvial gravitational load from the analysis of the monitoring data and the field of information collection. And landside has a tendency to continue to deformation. In rain season,the landslide deformation rate can be increased and become a risk of potential sliding mass. The corresponding protection work is necessary.
