摘要
焦家金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,近几年抓住黄金价格较高的有利时机,进行已采完主矿体下盘低品位矿石的单独回收和主矿体尚未回收矿体的同步回收工作,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。
Jiaojia gold plate under the main ore occurrence of the large scale and relatively low grade ore geological resources,higher gold prices in recent years to seize the favorable opportunity to complete the main ore body has been taken under a separate set of low grade ore Recycling and the main ore ore body has not yet recovered the synchronization recovery,and reduce the rate of decline in mining field,to extend the service life of mine effect is obvious,not only the full recovery of the national mineral resources,and the obvious economic benefits of mining to other similar cases have good of reference.
