| 摘 要： | 结合镜铁山矿桦树沟矿区应用截止品位放矿和无（低）贫化放矿工艺存在的问题,分析了截止品位放矿、无（低）贫化放矿的缺陷。总结提出了截止品位和出矿总量控制相结合的放矿方法,经过6年的实践证明,矿石出矿品位稳定,回采率得以大幅度提高,可供同类矿山借鉴参考。

| Abstract: | In combination with some problems on application of cut-off grade ore drawing and no(low) dilution ore-drawing process in Huashugou mining area of Jingtieshan Mine,the defects on the cut-off grade ore,no(low) dilution drawing are analyzed.A combined ore-drawing method of the cut-off ore grade and ore out-let control was proposed.After six years of practice,the ore grade from mine is kept stably and the recovery rates are significantly increased,which is available for reference of similar mines. |
