英古列茨采选公司是克里沃罗格矿区用露天法高效率开采铁矿石的企业典型。1966年,克里沃罗格矿区设计院完成了英古列茨采选公司露天矿年产3000万吨原矿的扩建设计。该公司的产量实际已达到3640万吨/年。1974年,为了保证公司露天矿下部各水平的产量继续增长,在露天矿的边坡上开凿斜井,在斜井内安装运输机系统,距地表100米深处安装乌拉尔机械制造厂生产的
The company, which is based in Ingolstadt, is an example of a company that exploits iron ore efficiently in the open air at the Krivoy Rogo mine. In 1966, the Kreywoluog Mining Design Institute completed the expansion design of an annual output of 30 million tonnes of ore in the open pit mine at Ingolstadt Mining Company. The company’s production actually reached 36.4 million tons / year. In 1974, in order to ensure that the production of the lower level of the Company’s open-pit mines continued to grow, slanting inclined shafts on open-pit mines, installing transport aircraft systems in inclined shafts and installing the Ural machinery factory at a depth of 100 meters from the surface
