摘　　要：在三维可视化环境下可快速实现矿体品位的高精度计算,直观体现矿体规模及矿体(矿化)的空间分布规律。本文基于DIMINE软件,利用易门铜厂矿区的坑道及钻孔资料建立地质数据库,运用地质统计学理论和块段构模方法创建铜厂矿体沿走向、倾向、厚度三个方向上的矿化数学模型。并用块段模型对Cu元素进行了品位推估,得出Cu品位空间分布模型,从三维角度更直观、准确地揭示矿体中铜品位在空间上的分布规律,为认识矿化分布规律提供了新依据。The ore body grade can be calculated quickly and precisely in the 3D visualization environment. The resulting model can give a visual representation of the orebody scale and the spatial distribution of ore grades. Based on the DIMINE software, this work has established the geological database using the exploration drilling data. We constructed a mathematical model of the ore bodies in three directions of the strike, dip and thickness by using the geostatistics and block modeling technology. Then we estimated the grades of copper and acquired the grade spatial distribution model. This model allows a more intuitionistic and precise view to the spatial distribution of copper grades of orebodies from the three-dimensional perspective and provides new evidence for describing the mineralization distribution rule.
