以地质统计学理论为基本工具,以三维栅格形式的矿体块体模型向其矢量形式的矿体几何结构模型转换,提出了一种矿体实体模型构建方法——克里格块体(KB)法.该方法对矿体内部相对稳定的矿石属性的空间分布情况进行了详细考查和评估;对特定约束条件下矿体三维块体模型的外部形态进行提取和重构,实现矿体实体模型的动态构建、更新及其表面地质属性的精细表达.理论分析和实际应用结果表明:对于大数多矿山,KB法都能够达到所期望的动态建模效果.
Based on the geostatistical theory as the basic tool, the orebody model in the form of a three-dimensional grid is converted to the vector form of the orebody geometry model. A new method for constructing the ore body model is presented - Krieger block KB) method is proposed in this paper.The spatial distribution of relatively stable ore properties within the orebody is investigated and evaluated in detail.The external shape of the orebody three-dimensional block model under specific constraints is extracted and reconstructed to realize the orebody entity Dynamic construction and updating of the model and the fine expression of its surface geological attributes.Theoretical analysis and practical application show that for the large number of mines, KB method can achieve the desired dynamic modeling effect.
