克里沃罗格矿区开采高品位铁矿石的矿井,1986年开采深度为755～1165m,而基建工作在地表下985～1568m 深部进行。富矿开采深度最近可能达到1500m,将来要达到2000～2500m。
The mining of high-grade iron ore in the Krivoy Rug Mine was conducted in 1986 with a depth of 755 to 1165 m and infrastructure work at a depth of 985 to 1568 m below the surface. The depth of rich ore mining may reach 1500m recently, and it will reach 2000 ~ 2500m in the future.
