摘要
基于孝义铝矿沉积型矿体特点及赋存条件,通过不同采矿工艺的对比,分析了液压反铲回采铝土矿的功效,证实了液压反铲对沉积型铝土矿回采具有高回收率、低贫化率等优点。该工艺对于缓倾斜薄矿体铝土矿、铁矿露天开采具有重要意义。
Based on analyzing the properties of Xiaoyi sediment type bauxite body and its occurrence conditions, different mining technologies are compared. It is found out that bauxite mining technology using hydraulic back-acting shovel has advantages such as high efficiency and low depletion rare. The rechnology is very useful for exploiting gentle- inclined thin bauxite body as well as for open--pit mining of iron ore.
