Prediction of potential slip mode of open-pit mine stope slope based on FLAC3D

Abstract：Aiming at the deformation cracks appearing on the south slope of the stope in Shengli East No.2 Open-pit Coal Mine,in order to accurately predict the potential slip mode of slope,the article carries out 3Dmine-Rhino coupling modeling using detailed geological condition information,establishes the heterogeneous true three-dimensional numerical simulation model of the south slope.The article studies the potential slip mode of the south slope using FLAC3D software for calculation.The results show that the current position of surface cracks and floor heave is basically consistent with the numerical simulation results,which verifies the accuracy of the simulation;the failure mode of the potential sliding body in the south slope is the circular-weak combined sliding with the Tertiary floor as the weak layer and the location of surface cracks and floor heave will develop to the west.
