苏联科夫多尔露天矿按封闭圈的设计深度为535米。工作台阶高度,+70米水平以上为12米,以下为15米。有三种类型的岩石:松散的、中硬的、坚硬的。松散岩石是砂-砾石-巨砾冰川沉积层(湖-海相沉积)和粘土、砂砾-粘土形成的风化壳,厚度12～25米。中硬岩石在不同程度上遭受到物理风化,风化
Soviet Coventhal open-pit mine by the closed circle design depth of 535 meters. Work bench height, 12 m above + 70 m, below 15 m. There are three types of rock: loose, medium hard, hard. Loose rocks are sand-gravel-boulder glacial deposits (lake-marine deposits) and weathering crusts formed by clay, grit-clay, and have thicknesses of 12-25 m. Hard rocks are physically weathered and weathered to varying degrees
