基于3Dmine探讨露天境界优化设计

Study on Optimized Design for Open-pit Boundary Based on 3Dmine

以包钢集团下属白云鄂博铁矿主矿为例,利用3Dmine三维矿业软件,建立地表模型、地质数据库、矿体模型、块体模型,在两种条件下,进行露天境界优化,选取境界优化结果,布置开拓运输系统,在综合考虑市场矿石销售价格波动和开采成本变化下,实现经济效益最大化。

Taking the main stope of iron ore mined in Bayan Obo of Baosteel Group as the sample, the terrain models, geological database, ore body models and ore block models were established by 3D mining software. Based on the two types of conditions, the optimization of the open-pit boundary was done so that the optimized data for the boundary were selected and furthermore the opening and transportation system was arranged and assigned. So the maximization of economic benefits was achieved in view of the fluctuations in prices at ore sales market and the variation in cost in ore mining.
