本文报道了格勒奇斯－格罗斯曼算法和浮动圆锥算法得出的露天矿设计分别同动态圆锥算法得出的露天矿设计对比的一项研究工作。对比研究的根据是最终露天矿总经济价值。文中叙述了这项研究的详细内容并且讨论了所得出的研究结果。研究结果表明：对比的各对算法中，每种算法都得出数个高于另一种算法的最终露天矿经济价值。结论是：露天矿优化设计的正确方法应当是采用数种不同的算法，然后从所得出的诸设计方案中选择价值最优的露天矿设计。
In this paper, a research work comparing the design of open-pit mines with the dynamic coning algorithm to the design of open-pit mines based on the Gletsch-Grossman method and the floating cone algorithm is reported. The basis for the comparative study is the total economic value of the final open pit mine. The article describes the details of the study and discusses the results of the study. The results show that in each pair of algorithms, each algorithm gives several economic values of the final open pit mine which is higher than the other one. The conclusion is: The correct method of OPM should be to adopt several different algorithms, and then choose the most optimal design of open pit mine from the design solutions.
