Abstract:

Abstract: 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.
