摘　　要：非洲某大型露天矿存在废石量巨大,排土场距离远,采场至排土场间地势陡峭、高差变化大等问题。为了寻求一种经济、安全、高效,对环境影响较小的废石运输方案,以当前先进且成熟的矿山运输技术为基础,借鉴国内外大型露天矿的生产运行经验,研究全汽车运输和汽车+破碎站+胶带联合运输2个方案的可行性,并在设备和基建投资、生产运营、环境保护3个层面进行量化对比分析。结果表明,汽车+破碎站+胶带联合运输方案较全汽车运输方案投资减少了1.05亿元,平均经营成本降低4 729.5万元,且对环境影响更小,为矿山建设经营提供决策依据。There are some problems in a large open pit mine in Africa,such as huge amount of waste rock,long distance of dump,steep terrain from stope to dump,and great variation of height difference.In order to seek an economic,safe,efficient waste rock transport scheme with less impact on the environment,based on the current advanced and mature mining transport technology,and drawing on the production and operation experience of large open pit mines at home and abroad,the feasibility of two schemes,namely,full automobile transport and automobile+crushing station+belt combined transport,are studied.Three lev⁃els of the equipment and infrastructure investment,production and operation,environmental protection are analyed quantitatively and comparatively analysis.The results show that the combined transportation scheme of automobile+crushing station+belt combined transport reduces the investment by 105 million yuan,the average operating cost is reduced by 47.295 million yuan,and the impact on the environment is less,which provides decision-making basis for mine construction and operation.
