| Abstract: | Based on the engineering geological investigation,the slope deformation of mind-out area in Yangjia colliery of Fuyang under natural state and after treatment was simulated with discrete element method.The distortion-destruction mechanism was analyzed for the flexural toppling of colluvial deposits in the front edge of the slope.Research shows that the slope can be basically kept in the stable state after protection. |

| Keywords: | mind-out area slope stability slope treatment discrete element method analysis method numerical simulation |
