摘要
针对石宝露天矿3个采坑采场最终边坡出现的不稳定现象,根据其工程地质和水文地质条件,并结合现场工程地质勘察和岩石力学试验,运用极限平衡分析法对其整个采场的最终边坡进行了详细的分析和研究。分析结果表明,石宝露天矿采场边坡均处于稳定状态,但是A、B、C、E、F、I、K、L 8个分区边坡从稳定性考虑,需要减缓边坡角,D、G、H、J 4个分区边坡角可提高,加陡时应考虑现场工程地质状况。
According to the instability of the final slope in 3 mining pits of Shibao openpit mine, the limit equilibrium method is used to analyze and stuay the final slope of the openpits, combining with the engineering geological and geohydrologie conditions, site engineering geological investigation and rock meehanies tests. The analysis shows that all of the final slopes are stable, while the slope angles of A, B, C, E, F, I, K, L slopes should be eut and those of D, G, H, J slopes can be increased.
