基于探矿者软件(Minexplorer)的三维地质建模及储量估算——以湘西北李梅铅锌矿为例

在全面收集地质资料的基础上,利用探矿者软件建立了湘西北李梅铅锌矿区的综合地质数据库,利用三维钻孔数据建立了研究区的三维矿床模型,并以矿体模型和地层模型为例,介绍了矿区三维地质建模的一般流程。在矿体模型的基础上,利用地质块段法、地质截面法、地质统计学方法进行了储量估算,并与矿山勘探报告中的储量估算结果进行了对比。研究结果表明,利用探矿者软件进行三维建模和储量估算,操作简便、可视化效果好,不同方法进行储量估算的结果互相印证,真实可靠。

Three-dimensional geological modeling and reserve estimation based on Minexplorer software in the Limei Pb-Zn Deposit, northwestern Hunan

In this paper, the integrated geological database was established based on overall collection and analysis of geological information using the Minexplorer software in the Limei Pb-Zn deposit of northwestern Hunan. A 3D deposit model was built mainly on 3D borehole data of the study area. Especially, the ore body model and stratigraphic model were taken as examples to introduce the general way for 3D geological modeling at the deposit scale. Reserve estimation was conducted based on the orebody model by using three methods, i.e., geological ore block method, geological section method, and geological statistics method. The results were compared with the results submitted in geological prospecting report of the deposit. It is proved that 3D modeling and reserve estimation using the Minexplorer software have several advantages such as convenience, better visualization and accuracy.
