| Abstract: | Based on the example of mining from open-pit mine to underground mine in Shilu mining area of Hainan Iron Mine,stress strain and stability of the slope of mining from open-pit mine to underground mine in this mining area before mining were analyzed by using the limit equilibrium method,the finite element stress method and the finite element intensity reduction method.The analysis of many methods obtained accordant results and showed that this slope was in a stable state currently. |
