| 摘 要： | 焦家金矿望儿山矿区曾用留矿法回采上部矿体,留存品位相对较低的残采矿石资源.针对残采低品位矿石资源进行采矿方法实验,恢复原有工程以降低采切工程量,采用副中段加中深孔爆破落矿的方法,成功回收了空区下盘低品位矿石资源,综合效益明显,可供其他类似情况的矿山借鉴.

| Abstract: | The shrinkage method had been used in Wangershan mining area of Jiaojia Gold Mine to stope upper ore body,and the residual ore resources was relatively low grade ore.The mining method experiment for residual ore resources with low grade was performed,and original engineering was restored to decrease the mining and cutting engineering quantities.The sublevel and medium-length hole ore blasting method was adopt to successfully recover ore resources with low grade in goaf footwall.The comprehensive benefits ar... |
