多因素条件下的露天矿最终境界优选

Optimal Selection of the Final Boundary of Open-pit Mine under Multi-factor Conditions

露天矿最终境界的选取是露天开采过程中的关键环节,直接影响矿山生产规模和矿山效益,传统最终境界选择多考虑利润和安全方面的因素,很少考虑矿山的可持续发展问题。基于Dimine数字采矿软件平台,构建露天矿山价值模型,采用网络最大流最小割算法进行露天境界优化,同时通过调节矿石价格产生多个嵌套境界,综合考虑经济、社会、环境等多个因素构建露天矿最终境界优选模型优选露天矿最终开采境界。方法的应用在保证矿石经济利益的同时,在实现矿山可持续发展及绿色开采方面具有较好指导意义和社会价值。

The selection of the final boundary of open-pit mines is a crucial process of open-pit mining, which directly affects the scale of mine production and mine benefits.The factors of safety and profit are more considerable in the traditional final boundary selection, however, the sustainable development rarely are considered. In this paper, based on the Dimine Digital mining software platform, the construction of an open-pit mine value model was established optimize the ultimate mining boundary of open pit mines, using the maximum flow/minimum cut algorithm to optimize the boundary of open-pit mining, and generated a multiple of nested boundaries by adjusting the ore price, at the same time, considering the economic, social, and environmental factors.The application of this method has good guiding significance and social value in realizing sustainable development of mines and green mining while ensuring the economic benefits of ore.
