Study of centralized mining model and integrated technology match mode not only is the development trend of modern open pit coal mine, but also is one of the problems large open pit coal mine in China facing currently. By analysi-sing exploitation of scale constraints comprehensively. With the objective of maximizing revenue to construct a single scale pit reasonable revenue function. By integer programming methods, established a multi-scale pit production model of the rational. And by analysising of Antaibao open pit,the results showed that the reasonable production scale of Antaibao was 22. Q Mt/a.%研究露天矿区集中化开采模式和综合工艺匹配模式既是现代露天煤矿的发展趋势,也是我国特大型露天煤矿目前所面临的问题之一.全面分析了开采规模的制约因素,并以收益最大化为目标,构造了单坑合理规模的收益函数,通过整数规划方法,建立了多坑的合理生产规模模型,并以安太堡露天矿为例进行了分析,得出安太堡露天矿合理生产规模为22.0Mt/a.
