克里沃罗格矿区中央采选公司开采铁石英岩的主要生产单位是1号和2号露天矿。在1号露天矿东部边坡,以地下法开采一组互相平行的矿体,矿体埋藏深度由几十米至1000米,厚度在80米以下,倾角50～70°(图1)。在2号露天矿范围内,在北部边坡不长的一段也进行地下开采。
The main production units for extracting quartzite from the central mining and mining company at the Krivoy Rug Mine are No. 1 and No. 2 open pit mines. On the eastern slope of No. 1 open pit, a group of ore bodies parallel to each other are mined by underground method. The depth of burial ore bodies is from tens of meters to 1,000 meters, and the thickness is below 80 meters with an inclination of 50 to 70 degrees (Figure 1). In the No. 2 open pit mine, underground mining is also carried out for a short period of time in the northern slope.
