大型铜镍矿矿物特征分布趋势变化建模分析

Large Copper Nickel Ore Mineral Features Distribution Trend Modeling Analysis

针对当前矿物特征分布趋势变化的建模技术无法完全准确地描述不同地质现象,不能直观地体现矿物特征分布趋势提出一种新的大型铜镍矿矿物特征分布趋势变化建模方法。介绍了大型铜镍矿地质概况,通过构建地质数据库,圈定二维线串模型,生成三维剖面组合线框模型。依据变异函数对铜镍矿矿物特征分布趋势进行建模分析,构建三维空间变异椭球体模型实现大型铜镍矿矿物特征分布趋势变化建摸。实验结果表明,所构建模型与实际矿体基本一致。

In view of the current mineral characteristics of the distribution trend of modeling cannot accurately describe the different geological phenomenon, can′t intuitively reflect characteristics of mineral distribution trend.Mineral characteristics put forward a new large copper and nickel ore distribution trend modeling method,the geological survey, large copper and nickel ore by building geological database, select 2D geological section line string model, generate 3D profile combination wire frame model were introduced.According to the variation function characteristics of copper and nickel ore mineral distribution trend modeling analysis, building three-dimensional space mutation ellipsoid model,the large copper nickel ore mineral feature modeling distribution trend change was realized.Experimental results show that the built model and actual ore body are basically identical.
