摘要
针对跑马坪2220中段滞留大量残矿和2220中段以下采矿方法的改变;对矿区的地质概况、残矿开采技术条件、残采方案、回采工艺和放矿管理进行了详细的分析。文中制定了合理的残矿回收方案,为2220中段以下无底柱分段崩落法采矿创造了条件。
According to the fact that a lot of residual ores are remained at 2220 m sublevel and the mining method is changed under 2220 m sublevel,the geological information,technical conditions of residual ores recovery,residual mining project,stoping technology and drawing management are detailedly analyzed in this paper.The reasonable residual mining project is conformed,which can create conditions for the mining of non-pillar sublevel caving method under 2220 m sublevel.
