苏联铁矿工业原料基地现状的特点是有用矿物储量大,埋藏条件好,大多数矿床靠近冶金工厂。所以,矿床的开发通常是从选择最有利的地区建设露天矿着手,然后将几个露天矿予以联合成为一个生产能力很大的露天矿。分期建设的特大型露天矿最有代表性和最有意义的实例,是所设计的克里沃罗格矿区南部含铁石英岩矿床群基地的苏别尔采选公司的年生产能力为1.5亿吨
The status quo of the Soviet Union’s iron ore industrial raw material base is characterized by large reserves of useful minerals and good burial conditions, and most of the deposits are near metallurgical factories. Therefore, the development of the deposit usually starts with the construction of an open pit mine in the most favorable area, and then combines several open pit mines to form a large open pit mine. The most representative and most significant example of the large-scale open-pit mine constructed by stages is the annual production capacity of Supor Mining Company, which is the base of the iron-bearing quartzite deposit group in the southern Kliwo Rogo Mine, Ton
