陕西楼房沟钒矿三维地质建模及找矿预测

Three-dimensional Geological Modeling and Prospecting Prediction of Loufanggou Vanadium Deposit in Shanxi

通过收集和分析楼房沟钒矿区已有的勘探工程资料,使用Surpac三维建模软件对楼房沟钒矿床的矿体建立了相应的矿体品位分布数学模型。并运用普通克里格法,对该矿床的品位和储量进行分析和估算,并将其结果与传统储量计算法的结果进行了比较和剖析。研究证明,可视化方法估算资源量更为客观、高效和快捷。结合建模工作并在深入了解矿床成因的基础上总结了成矿规律,指出了各矿床的找矿远景区段。

By collecting and analyzing data of the existing exploration data of Loufanggou vanadium ore district , the grade distribution mathematical model for the orebody was established using three-dimensional modeling software Surpac soft .And using ordinary Kriging method , the the grade and reserves were analyzed and estimated , the result of which was compared and dissected with that based on traditional calculation method .Results prove that the visualization method is more objec-tive , efficient and fast to estimate the resource reserves .Combined with this modeling work and the basis of thorough understanding of the ore deposit genesis , the metallogenic regularities were sum-marized, and the perspective sections for deposit prospecting were pointed out .
