黑色冶金是国民经济中最重要的部门之一,是工业生产与建设的基础。1975年全世界的钢产量超过了7亿吨,即在近十五年内钢产量增长了一倍。1980年苏联的钢产量将达到1.6—1.7亿吨。为了以优质铁精矿供应本国冶金工业以及满足出口的需要,必须把原矿的开采量增加到5.6亿吨,此时商品矿石的生产将增加20—25%。黑色冶金原料基地的发展仍需依靠建设一批采用露天开采法及深选工艺的年处理原矿
Black metallurgy is one of the most important sectors in the national economy and the basis of industrial production and construction. In 1975, the world’s steel production exceeded 700 million tons, that is, steel production doubled in the past 15 years. The steel output of the Soviet Union in 1980 will reach 160-170 million tons. In order to supply its domestic metallurgical industry with high-quality iron ore concentrate and to meet its export needs, it is necessary to increase the amount of ore mined to 560 million tons and the production of commercial ore will increase by 20-25%. The development of black metallurgical raw material base still needs to rely on the construction of a group of open-pit mining methods and deep processing of the annual processing of ore
