  • 锦丰金矿充填系统改造及应用……章海象,王征
  • 摘 要:针对锦丰金矿全尾砂—人造砂结构流体胶结充填系统存在的人造砂原材料供应、尾矿库库容压力及环保、充填料浆容易沉淀及离析、充填管道磨损、充填体强度低等问题,进行了分级尾砂胶结充填工艺改造。详细介绍了充填工艺系统及改造过程。改造后的充填工艺系统圆满解决了露天矿闭坑后出现的充填骨料供应问题,减少了排入尾矿库的浮选尾矿量,缓解了尾矿库的库容压力。同时,因为取消了人造砂,不再产生人造砂制备费用,降低了矿山的充填生产成本。

    Renovation andapplication of filling system in Jinfeng Gold Mine……Zhang Haixiang,Wang Zheng

    AbstractThere areproblems concerning raw material supply of artificial sand,tailings reservoircapacity and environmental protection,easy precipitation and dissolution offilling pulp,filling pipe wearing and poor filling body strength in theungraded-tailings-artificial sand structural fluid cement filling system ofJinfeng Gold Mine.In light of that,renovation with graded tailings cementfilling technology was carried out.The filling system and the renovationprocess were introduced in detail.The renovated filling system completelysolves the short supply of filling aggregates taking place after open pit closure,reducesthe discharge of flotation tailing into the tailings reservoir,mitigates thepressure imposed on tailings reservoir capacity.At the same time,since theartificial sand is canceled,the cost of artificial sand preparation issaved,lowering the filling operation cost for the mine.
