摘要: 采空区处理及矿柱回采关系到生产的连续性及安全性。针对青铜沟汞锑矿550中段大型高品位矿柱残留的问题,首先回采前使用人工混凝土矿柱支护空区,施工方案根据经验公式进行设计与稳定性分析,结果可行;其次保留原有点柱及大型矿柱中的部分点柱支撑顶板岩体;最后采用嗣后全充方案,充填整个采空区。该方案既保障人员作业过程中的安全,又争取高品位矿柱尽可能全部回收。

Abstract: The goaf treatment and pillar recovery are related with productive continuity and safety.In view of existing situation that large and high-grade pillars are left over in the production stage 550 in Qingtonggou Mercury-antimony Mine,firstly artificial pillars are used to support the goaf.According to the empirical formula,the construction was designed.Through the stability analysis,the result is seen rational and feasible.Secondly,the intrinsic point-pillars and partial point-pillars of the large pillars are reserved to support the roof.Finally,back-filling fills the whole goaf.This method ensuresd that the workers safety in the work processes and winned over the high-grade pillars recovered entirely as possible.
