摘要
针对某铁矿具体情况,提出了采用浅孔留矿与阶段空场联合采矿的方案,并在矿山进行了采矿实践。结果表明该方法可大大降低矿山后期选矿成本,原矿采选综合成本降低了20元/t,取得了一定的应用价值与经济效益,为特殊矿石类型的分采提供了新思路。
This paper raises a mining scheme by using shrinkage ＆ block stoping method and conducts it in Yinggezui Iron Mine. It turns out that the cost for mining and mineral processing is cut down greatly by 20 yuan per ton, by which, application value and good economic benefits can be achieved, which also offers new ideas for mining and separating special ores.
