摘要
应用地质统计学的理论和方法,借助矿床数学模型软件,利用三维数值模拟技术建立了云南省金平白马寨镍矿Ⅲ号矿体的深部矿体模型.模型清楚地体现了矿体的形态、产状和成矿元素分布特征,模拟结果与实际矿床基本特征吻合较好,并在此基础上进行了矿体的深、边部成矿预测.该研究表明基于数字矿床模型的研究方法在深部勘探过程中具有很好的实用性.
Based on the theory and methods of geostatistics and with the software package of the mathematic model for ore deposit,a 3D digital modeling was established for certain ore body in Baimazhai Ⅲ ore body of Jinping,Yunnan province.A comparision of the modeling results with the real deposit showed the accuracy of the modelling.The results indicate that it is easy to know the form,dimension and distributing characteristics of the chemical composition of the ore body with this model,which provides a foundation for dynamically calculating reserves of bounding ore body.This study also demonstrates the unique advantage of the digitalmineral deposit model inmineral exploration ofmines at depths.
