针对南芬露天铁矿多分期多分区开采的特点,把不同分期分区的剥岩相结合,适时调整出入沟标高,建立近距离低标高运输通路,降低矿车的柴油消耗,避免追加矿山运营费用,经济效益可观,在同类矿山发展中有一定的参考价值。
According to the characteristics of multistage and multi-section mining in Nanfen open-pit iron mine, it is necessary to combine the stripping and rock-breaking of different staging areas to adjust the ditches and elevation at a suitable time to establish a low-altitude transportation route at a short distance and to reduce the diesel consumption of the mining vehicle and to avoid additional mine operation expenses , Considerable economic benefits, in the development of similar mines have some reference value.
