2) mining room
回采空间
1.
Different level of double mining room was experimented in 15~# gold ore veins which belongs to Jinchanggouling gold mine,ores geological serial number was 9154,used this method was to solve mining difficult problem in expansion and shrinkage with branching complex gold ore veins.
不同位双回采空间试验应用于金厂沟梁金矿15#脉,矿块地顶编号9154,应用该法主要是为了解决矿脉分枝复合膨缩严重的矿块回采问题,同时也能提高矿石的回采回收率,提高采矿回益,并为回采类似地质状况的矿块积累经验。
3) open stope mining
空场回采法
4) dip retreat
沿倾斜后退式回采
1.
The employment of dip retreat and wedge pipe bolt for roof support showed that the permissible exposed area of mine goaf increased from 50m2 to 258-500m2, thus greatly reduced the ore loss and dilution.
本文以理论研究为基础,密切结合生产实际,采用沿倾斜后退式回采顺序和楔管式锚杆护顶技术,使采空区允许暴露面积只有50m~2左右,扩大到258～500m~2,大幅度地降低了矿石损失与贫化,获得显著的经济效益。
5) along the goaf and road
沿空沿底
6) space of mined-out area
实际回采空间
