在开采过程中,一个静脉是薄的,下部的围岩,岩石在采场手选择,充填到井里。由横撑和废石充填体的一部分,支持下盘岩石。矿石开采,选择了一些浪费,降低了稀释率。每个填充威尔斯可容纳144t废弃物,木材消耗2.2m3。 静脉较薄,围岩和围岩不稳定,采用控制爆破技术是很重要的。在布置形状的孔,60度的倾角、最小抵抗线0.6m,孔间距0.8m,行距0.5m,孔神0.8m、50%的收费系数,一层高度0.7m。
In mining, a vein is thin, lower part of the surrounding rock, rock in stope hand selected, filling into the well. By the cross brace and waste rock filling body part, support the footwall rocks. The ore mining, selected some waste, reduce the dilution rate. Each filling wells can accommodate 144t waste, wood consumption 2.2m3. The vein is thin and the ore and surrounding rock is not stable, it is important to use control blasting technology. Hole in the shape of the arrangement, the dip angle of 60 degrees, the minimum resistance line 0.6m, hole spacing 0.8m, row spacing 0.5m, Kong Shen 0.8m, charge coefficient of 50%, a layer of height 0.7m.
