摘要
雄村铜金矿床是目前在西藏冈底斯成矿带上发现的唯一一个岛弧型斑岩铜矿,具有较高的经济及科研价值。针对雄村Ⅱ号矿体资源储量估算方法进行了对比研究,分别利用平行断面法和统计学方法中的距离幂次反比法、普通克里格法估算矿体资源储量,其中统计学方法的实现主要借助于Micromine三维地质建模软件,最终得到的估算结果基本一致。通过对传统法和统计学法具体实现过程及原理的对比,统计学方法不仅考虑到矿体的外部形态,还考虑到了矿体内部品位的变化性质,在实现过程中更为直观,其灵活的图形处理方式能够很好的满足不同阶段、不同规范下的资源储量估算工作要求,具有广阔的应用前景。
The Xiongcun copper-gold deposit is the only island-type porphyry copper-gold deposit discovered on the Gangdise metallogenic belt,which has high economic and scientific value.A comparative study on the estimation methods of the reserves of the Xiongcun No.Ⅱorebody was carried out.,The distance Power Inverse Ratio Method in the parallel section method and Kriging Method of statistical method in the statistical method were used to estimate the orebody resource reserves respectively.The realization of statistical method is mainly based on Micromine three-dimensional geological software.The final results are basically the same.By comparing the concrete realization process and principle of traditional method and the statistical method,the statistical method not only takes into account the external shape of orebody,but also the changing nature of the orebody’s internal grade,which is more intuitive in the process of realization,and its flexible graphics processing mode can meet the requirements of estimating the resource reserves under different stages and specifications.It has a broad application prospect.
