摘　　要：以系统工程理论为指导,结合露天矿生产中存在的实际问题,提出了递阶优化的方法,即通过分范围、分目标、逐步深入的方法实现露天矿开采程序的优化,并对安家岭露天矿首采区的开采程序进行了多方案设置及技术经济评价.结果表明,在原设计前期900m工作线基础上采用陡帮开采方式对4煤以下采区南帮向里收缩200m,为当前条件下的最优开采方案.Based on the theory of systems engineering and combined with the actual situation of the process of open pit, an multi objective and grading optimization procedure of mining sequence for open pit is introduced and applied to Anjialing Open pit Coal Mine. Based on the present condition, the optimum mining sequence is that the pit bottom is contracted 200 meters from the south slope and slope angle is added under No 4 coal seam. The case study presented in this paper demonstrated the method of gradual optimization is simple and practical for optimum selection of mining sequence of open pit.
