摘　　要：针对南芬露天铁矿开采扩帮过渡的现实问题,设计考虑采用分区陡帮开采工艺。该工艺根据露天开采终了境界,将采场分为多个开采区域,合理安排分区的采剥顺序,均衡生产剥采比,从而达到以矿养矿、滚动发展的目的,切实提高矿山的经济效益。In view of the practical problems in the transition of slope expanding in Nanfen Open-pit Iron Mine,the technology of steep slope mining by areas is considered in the design.According to the ultimate pit limit of open-pit mining,in this technology the open pit is divided into several mining areas,the mining and stripping sequence of each area is reasonably arranged,and the stripping ratio in production is in a balanced way,so as to achieve the purpose of maintaining the simple re-production of the mine and making the mine develop at a progressive speed with specified amount cost extracted from the cost per ton of ore produced and effectively improve the economic benefits of mines.
