一、露天矿的建设克里沃罗格采选联合企业的露天矿开采品位为33—38%的含铁石英岩。复盖层为松散第三纪层和第三纪后期的沉积层(粘土和砂土),其厚度为10—40米。氧化带深度在各矿床之间及一个矿床之内均有变化,其波动范围为8—100米,有些地方甚至比勘探深度还深一些。围岩主要是片岩(表1)。
First, the construction of open pit mining Klivorod mining complex joint venture opencast mining grade 33-38% of iron-bearing quartzite. The overburden is a loose Tertiary and Late Tertiary sediment (clay and sand) with a thickness of 10-40 meters. The depth of the oxidation zone varies between deposits and within a deposit, fluctuating in the range of 8-100 meters and in some places even deeper than the depth of exploration. Surrounding rock is mainly schist (Table 1).
