利用大型矿业软件Surpac创建了某矿深部矿床的地质数据库,建立了该矿深部矿体的三维实体模型和品位块体模型,采用普通克里格法对矿床有用元素进行了估值,获得了矿体Pb、Zn、S平均品位的空间分布及边际品位与Pb、Zn、S平均品位的关系。按不同边际品位和不同中段对矿床地质储量进行了统计计算,并将矿山生产实际获得的储量与计算获得的储量结果进行了对比分析。结果表明,所建立的矿床三维模型、品位推估及储量计算结果可靠,可用于辅助矿山开展资源评估、采矿设计以及开采计划编制等工作。
Using the large-scale mining software Surpac, a geological database of a deep ore deposit in a mine was established, a three-dimensional solid model and a grade block model of a deep orebody in the mine were established, and the useful elements of the ore deposit were estimated by the common kriging method. Spatial distribution of Pb, Zn, S average grade and the relationship between marginal grade and average Pb, Zn, S grade. According to different marginal grades and different middle sections, the geological reserves of the deposit were calculated and the actual reserves of the mine production were compared with those of the calculated reserves. The results show that the established three-dimensional model of the deposit, the estimation of the grade and the calculation of the reserves are reliable and can be used to assist the mine in resource assessment, mining design and preparation of the mining plan.
