摘要
本文以矿区已有的地质资料为基础,应用三维地质建模的思路,建立了都匀大梁子铅锌矿的地表模型、断层模型、勘探工程模型、矿体模型。用Surpac软件下的块体模型法和地质块段法对大梁子铅锌矿的(Ⅱ1、Ⅱ2、Ⅲ1、Ⅲ2号矿体)的资源量进行了估算,并对两种计算结果进行了比较分析。结果表明:三维地质块体模型法在计算块体资源量是要比传统的地质块段合理一些,其优势在于其可以直观地表现出矿体品位在三维空间的变化规律,可视化效果明显,并对后期的勘查和开发具有一定的指导意义。
This paper establishes the surface model,fault model,exploration engineering model,ore body model based on the theory of modern metallogenic prediction and the existing geological data of the mining area.Estimated the lead-zinc resource reserves of the Daliangzi lead-zinc mine by using the block model method and the geological block method by Surpac software,and Compare and analyze results shown that the three-dimensional geological block model method is more reasonable than the traditional geological block,and its advantage is that it can visually show the change rule of ore body grade in 3Dspace,and the visual effect is very obvious,and it will has a certain guiding significance for late development.
