摘　　要：昆钢大红山铁矿主矿体下盘赋存着规模较大而地质品位相对较低的矿石资源,为了提高资源的综合利用率,现单独对已采完主矿体下盘低品位矿石回收和主矿体尚未回收完的低品位存隆矿同步进行回收工作,对降低采场下降速度、延长矿山服务年限效果明显,不仅充分回收了国家矿产资源,并且经济效益明显,对于其他类似情况的矿山有很好的借鉴作用。Kungang Dahongshan iron ore main orebody footwall occur with larger scale and the relatively low mineral resources,geological grade in order to improve the comprehensive utilization of resources,has picking main orebody footwall separately for low grade ore recovery and the main ore body has not yet been recovery of low grade deposit synchronous recycling long mine,the stope for the decreasing speed,service life of mine effect is obvious,not only fully recycle the national mineral resources,and the economic benefit is obvious,for other similar mines has a good reference.
