露天矿深部开采边坡稳定性分析与治理方案研究

Analysis of Slope Stability in Deep Mining of An Open-pit Mine and Its Control Scheme

某露天铁矿目前已进入深部开采阶段,边帮岩体多处出现张裂、滑塌,使下方台阶不能按设计靠界并段,严重影响了矿山的生产能力。根据现场地质状况分析、试验研究和理论计算,对该矿深部开采对边坡稳定性的要求进行研究,同时有针对性地提出边坡综合治理方案,并对加固后高陡边坡进行稳定性分析。

A certain open-pit mine has come into its deep mining stage. As split and slide have occurred in many places of the slope rockmass, the benches below it cann′t approach the boundary and realize section-combination as the design , seriously affecting the mine production capacity. Based on the analysis of the site geological conditions and by experimental research and theoretical calculation, study is made on the requirements of the deep mining of the mine on the slope stability. The scheme for comprehensive control of the slope is proposed and the stability analysis is made on the highly steep slope after reinforcement.
