露天边坡富矿开采采场结构参数优化分析

会东铅锌矿在露天开采的同时，对西南部边坡内富矿段用上向分层胶结充填采矿法进行开采。为有效地开采该富矿段，控制这种开采对边坡稳定性的不利影响。对开采过程用三维有限元进行了分析，并根据分析结果用正交极差方法研究了采场结构参数和稳定性评价指标，提出了合理的采场结构参数和充填体强度要求，指明了应加固的部位。

Analysis of stop Structure Parameters Optimmization for Rich ore Mining in Open Pit Slope

While open ming was conducted in Huidong Lead Zinc Mine,the rich ore section in southwest slope was extracted with overhand cemented cut and fill mining method.In order to mine the rich ore section effectively and control the disadvantageous effects of this mining on the stability of slope,a three dimensional finite element method was used to analyze the mining process and an orthogonal raneg method was used to study stope structure parameters and the evaluation index of stability in light of the analysis results,so as to put forward reason able parameters of stope structure and the strength requirement of fill mass and defermine the locations to be consolidated.
