露天煤矿边坡失稳条件下恢复正常开采工艺

Resume Normal Mining Process Under Slope Instability Condition of Open-pit Coal Mine

摘要: 以内蒙古地区某失稳边坡露天煤矿为研究对象,以边坡变形实时监控预警为安全保障措施,划定3个开采阶段,分阶段选取不同的安全储备系数,确定各阶段开采工艺及停采位置,进而确定了恢复正常开采工艺的空间节点,其研究思路及计算方法可为露天煤矿近似问题的解决提供借鉴。

Abstract: Taking a open-pit coal mine slope instability of Inner Mongolia region as a research object and the real-time monitoring and early warning of slope deformation as the safety guarantee measure, this paper demarcates three mining stages, selects different safety reserve coefficients in stages, determines the mining process and stop-mining location in each stage, and then determines the spatial node to restore the normal mining process. The research idea and calculation method can provide reference for solving the approximate problem of open-pit coal mine.
