斯梯坊敦矿经过26个工作日大规模集中回采试验完全证明:如果矿脉在经济上及地质条件方面均适于这种方法,则集中回采的效果是良好的。斯梯坊敦矿,正常的选矿处理量,每月约为205,000吨手选后的矿石。这预先就要从110个采区中每月推进39300米,平均每月工作面推进速度为4.9—6.4米。在3月份的试验中,90.5%的正常进尺只是从六个采场中采出的。这表明,现在的生产规模,在矿山的较小范围内就能够完成。此试验也提供了有价值的资料,便于作将来的开采计划,以求得在今后几年内进行集中开采计划时,进行采准和回采的全盘革新。
After 26 working days, a large-scale centralized recovery test of the Si Tufangtun Mine fully proved that if the veins are suitable for this method in economic and geological conditions, the effect of centralized recovery is good. Sifangfangdun mine, the normal dressing capacity, about 205,000 tons per month after hand-picked ore. This will advance 39300 meters per month from 110 mining areas, the average monthly work surface advancing speed of 4.9-6.4 meters. In the March test, 90.5% of normal footage was taken from only six stopes. This shows that the present scale of production can be accomplished within a relatively small area of the mine. This test also provides valuable information for future mining plans in order to achieve a comprehensive innovation in mining and mining when conducting centralized mining plans in the coming years.
