库尔斯克磁力异常区采选公司古布金矿采用下向垂直深孔崩矿、沿平底柱倾斜面出矿、BBДP-5型振动给矿机放矿的高效率阶段房式采矿法开采科罗布科夫矿床的含铁石英岩。矿房尺寸为55×30×50米,房间矿柱宽20米,盘区矿柱宽25米,在-65～-125米阶段内进行回采。该矿多年来持续地取得了较高的技术经济指标:1987年全矿工人劳动生产率为25.1吨/工班,工作面工人劳动生产率86.0吨/工班,1吨原矿的开采成本2.567卢布。近5年
Kursk magnetic anomaly zone mining company Cubu gold mine using the next vertical deep-hole collapse, along the flat-bottom inclined surface mining, BBДP-5-type vibrating ore beneficiation high efficiency stage mining mining Keruo Bu Iron ore quartzite in the Cobh deposit. The mine size is 55 × 30 × 50 meters, the ore column in the room is 20 meters wide, and the ore column in the plate is 25 meters wide. The mining is conducted within the period of -65 ~ -125 meters. The mine has consistently achieved high technical and economic indicators over the years: in 1987 the miners ’labor productivity was 25.1 tons / working class, the working face workers’ labor productivity was 86.0 tons / work class, and the production cost of one ton of ore was 2.567 rubles.
