Based on theoretical analysis of combined bench in open-pit mine, the author defined the significance of implementing the combined bench mining, determined the parameters of combined bench mining. The mine compared the effects of different programs on open-pit mine production, which provided reference for the implementation of combined bench mining.%通过对露天矿组合台阶的理论分析，明确了实施组合台阶开采的重要意义，确定了组合台阶开采的参数。对比不同开采方案对露天矿生产的影响，为露天矿实施组合台阶开采提供参考依据。
