摘要
为进一步研究抚顺西露天矿边坡稳定性,采用岩石力学实验、边坡稳定反分析等数据,利用极限平衡量分析法对抚顺西露天矿边坡进行研究,构建了数值模型,通过对西露天矿坑6个计算剖面的计算,得出西露天矿边坡的安全系数;并对计算剖面进行了边坡稳定性初步验算。验算结果表明:各剖面线安全储备系数大于1.05,境界内开采区域边坡满足生产安全储备要求。
In order to further study the slope stability of Fushun West Open-pit Mine,the article adopts the data of rock mechanics experiment and back analysis of slope stability,uses the limit equilibrium quantitative analysis method to study the slope of Fushun West Open-pit Mine,and constructs the numerical model.Through the calculation of six calculation sections of West Open-pit Mine,the article obtains the safety factor of slope,and preliminarily checks the slope stability of the calculation section.The results show that safe reserve coefficient of each section line is greater than 1.05,and the slope of the mining area within the boundary meets the requirements of production safety reserve.
