伏龙芝矿务局各矿井所开采的矿床是克里沃罗格矿区地质条件最复杂的矿床之一。埋藏条件不稳(倾斜52°~70°)、矿体分散、矿石与围岩的物理力学性质多变(硬度f=3~18)。
One of the most complex geologic conditions in the Krivoy Rug Mine is the deposits mined by Fronzaga Minerals. Buried conditions are unstable (inclination 52 ° ~ 70 °), ore bodies are dispersed, and the physical and mechanical properties of ores and surrounding rocks vary (hardness f = 3 ~ 18).
