基于极限平衡法的采场边坡安全稳定性研究

Study on Safety and Stability of Slope in Stope Based on Limit Equilibrium Method

在二维条件下,运用极限平衡法对鞍钢集团齐大山铁矿采场边坡的安全稳定性进行了分析,并将二维条件下的极限平衡法分析结果转换为可描述三维环境中的采场安全稳定性,对安全生产具有重要意义。

The safety and stability of slope in the stope of Qidashan Iron Mine of Ansteel Group Corporation were analyzed under the two-dimensional conditions by using the limit equilibrium method and meanwhile the analysis results by the limit equilibrium method under the two-dimensional conditions were changed into the state on safety and stability of the stope which could be described under the three-dimensional environment,which was of great significance to the safety in production.
