科夫多尔采选公司“铁”矿山采掘工段正在露天采场内进行矿石开采和岩石剥离。所开采的矿层形状复杂,很不规则,外部轮廓曲折多变。矿层倾斜70°～90°。目前,采场深度约为200m。由于搞矿石综合利用,要求必须按一些组分(铁、五氧化二磷和镁等)将开采的矿石混匀,致使采掘过程变得很复杂。由于对配矿成分的技术条件限制甚严,要求采场内同时用于开采矿石的电铲不得少于5台,转载混矿场上
Mining and rock excavation are being carried out in the open pit at the “Iron” mine in Cobdall mining and dressing company. The shape of the mining seam is complex, irregular and the external profile is tortuous. Tilting seam 70 ° ~ 90 °. At present, the stope has a depth of about 200m. Due to the comprehensive utilization of the ore, it is required that the mined ore must be mixed according to some components (iron, phosphorus pentoxide and magnesium, etc.), resulting in the complexity of the mining process. Due to the composition of the ore with very strict technical conditions, requiring the same time for the mining of mining shovel electric shovel shall not be less than 5 units, reproduced mixed mine
