Abstract
The slope stability problems of combined open-pit with underground mining is such a key technology and the core problem of mining safety production. This paper apply the numerical simulation analysis on engineering project, and using Midas, FLAC3D and other software analysis the slope stability, slip deformation characteristics and follow trends of combined open-pit with underground mining mining systematically. Due to the impact of both the underground mining and open-pit mining, the surface subsidence curves is multiple sink basins of different sizes, so the rock slope deformation extent of different regions is different. We find that the damage of the overlying rock is different during the the exploitation stage, indicate that with different mining thickness has important influence of the damage of the overlying rock, so the slope stability evaluation requires a combination of the specific circumstances of the project to analysis and evaluation of exploitation.
