江西石竹山硅灰石矿床X号矿体三维地质建模及资源量估算

3D Geological Modeling and Resource Estimation of X Ore Body in Shizhushan Wollastonite Deposit,Jiangxi Province

为开展石竹山硅灰石矿床X号矿体三维地质建模及资源量估算,使用地质图、勘探线剖面图等多源数据进行研究并建成地层和矿体的三维模型,然后采用克里金插值算法进行资源量估算。结果显示,建立的矿体三维立体模型可以更直观地看到矿体的空间形态分布;基于矿体三维模型,经过克里金插值法估算X号矿体的硅灰石资源量约为252.25万t。本次资源量估算全程使用Micromine软件进行分析,相比传统方法效率更高,三维矿体可视化对矿体进行分析能更加清晰、快速,而且效率高、出错率低。三维模型还可动态更新矿体,为后续探明矿体随时提供新的储量估算。

In order to carry out 3D geological modeling and resource estimation of the X ore body of the Shizhushan wollastonite deposit,multi-source data such as geological maps and exploration line profiles are used to study and build 3D models of the strata and ore body,and then Kriging interpolation algorithm is used to estimate the resource.The results show that the established 3D model of the ore body can more intuitively see the spatial morphology distribution of the ore body.Based on the 3D model of ore body,the wollastonite resource of ore body X is estimated to be about 2522500 t by Kriging interpolation method.The entire process of resource estimation is analyzed using Micromine software,which is more efficient than traditional methods.3D ore body visualization can analyze ore bodies more clearly and quickly,with high efficiency and low error rate.The 3D model can also dynamically update the ore body,which provides new reserve estimates for future exploration of the ore body at any time.
