科夫多尔采选公司露天矿的技术改造,生产工艺和组织的完善,主要和辅助作业的机械化,保证了矿山的高速度发展,12年内矿岩处理量增加1.7倍。采矿规模扩大和运输能力的增长是在采掘过程的费用不断提高和采掘条件日趋复杂的情况下实现的。在封闭等高线内露天矿的深度从1976年的100米增加到1984年的160米。而汽车运输距离则从2.5公里增加到3.6公里。采出矿岩总量中
The technological transformation of the open pit mine at Cobdu Dolomite, the improvement of its production technology and organization, and the mechanization of its main and auxiliary operations ensured the high-speed development of mines. The amount of ore rock processing increased by 1.7 times within 12 years. The expansion of mining capacity and the growth of transport capacity have been achieved with the continuous increase in the costs of extraction and the increasingly complex mining conditions. The depth of open pit mines in closed contours increased from 100 meters in 1976 to 160 meters in 1984. The car transport distance increased from 2.5 km to 3.6 km. Mining the total amount of ore
