基于DIMINE的印尼某红土镍矿床三维模型构建

摘要

运用DIMINE软件建立了印度尼西亚某红土镍矿的钻孔数据库,进行了样品组合,并在此基础上构建了矿区地表和矿体三维模型,然后利用实体模型约束建立了品位块体模型,采用距离幂反比法对矿体镍元素品位进行估值,对块体模型镍品位进行了统计,并对该红土镍矿床储量进行统计,最后将DIMINE地质统计学法矿量计算结果与断面法计算矿量结果进行比较.对比结果表明,DIMINE软件的计算结果准确可靠,可用于矿山的采矿设计以及储量资源的管理,并且能够大大提升设计水平和速度.%The Indonesia laterite drilling database was established by using DIMINE software. On the basis of the sample combination, the mining surface and orebody 3D model was built.The grade block model was set up by using physical model; the ore body grade of nickel was estimated by the distance power inverse ratio method, the nickel grade of block model and the laterite nickel ore reserves was counted. Finally, the results of ore quantity calculation by dimine geostatistics method and section method were compared. The comparison results show that the calculation results of DIMINE software are accurate and reliable, which can be used for mining design and reserve resource management, and can greatly improve the design level and speed.
