中文摘要:
      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。此次针对雄村II号矿体资源储量估算方法进行对比研究,分别利用传统几何法和统计学方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,最终得到二者的估算结果基本一致。通过对两种方法具体实现过程及原理的对比分析表明,无论是理论还是在具体实现过程中,统计学方法相比传统法有更高的精确度,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。
英文摘要:
      The Xiongcun copper-gold deposit is the only island-type porphyry copper-gold deposit discovered in the Gangdise metallogenic belt, which has high economic and scientific values. Aiming at estimation methods for No.II ore-body reserves of the Xiongcun, this paper attempts to use the parallel section method, Distance Power Inverse Ratio Method and Kriging Method of statistical method respectively for estimating ore resources reserves. The realization of statistical method is mainly based on Micromine three-dimensional geological software. Finally both of the results are basically the same. By comparing the concrete realization process and principle of traditional method and statistical method, the latter method not only takes into account the external shape of ore body, but also the changing nature of the ore body’s internal grade, because it 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, and has a broad application prospect.
