红土型铝土矿具有矿床储量大、平面面积大的特点,易于大规模露天开采,但矿层上部铁帽较硬,下部红土较软,不适应传统的穿孔、爆破采矿工艺。结合几内亚某红土型铝土矿的工程实例,研究了采用露天采矿机开采红土型铝土矿的可行性,并对此类型矿床的开拓运输方案进行了比较。研究表明,选用露天采矿机作为采剥设备,配合汽车+胶带联合运输,在技术上是可行的,经济上也能达到较好的效果。

Lateritic bauxite has the characteristics of large deposit reserves and large area and easy for open pit mining on a large scale, but upper gossan of ore bed is too hard and lower laterite is soft, therefore, traditional mining technologies of drilling and blasting are not applicable. By combination of engineering example of lateritic bauxite in Guinea, the paper investigates the feasibility of lateritic bauxite mining by using surface miner, and compares development and transportation schemes of this kind of deposit. The research shows that it is feasible in technology by selection of surface miner as stripping machine and application of combination transportation of truck and belt, and it can reach better benefit in economy.
