摘要
岩石的提前混入使得矿石过早贫化,研究分析发现导致镜铁山矿桦树沟矿区岩石提前混入的主要原因是推排、大块卡堵放矿漏斗、不合理的出矿方法以及端部放矿废石移动规律。本文结合镜铁山矿的实际生产经验对这4种导致岩石提前混入的主要原因的作用机制进行分析,提出对应的预防措施。
The advanced rock mixed in ore made the ore dilution early. The study and analysis found that the main reason of causing advanced rock mixed in ore in Huashugou mining area of Jingtieshan mine were unbroken ore wall, bulk jammed hopper, unreasonable ore drawing way and the waste moving law in the end discharge. In this paper, combined with the production practice of Jingtieshan mine, the action mechanism of advanced rock mixed in ore was analyzed, and the preventive measures were put forward.
