摘　　要：文章以MICROMINE软件为操作平台,以西藏三个大型矿床实例,通过四方面的对比,总结分析了传统几何法与地质统计学法2类资源储量估算方法的优缺点。与传统几何法相比,在理论方面,地质统计学法通过变异函数进行品位插值更加科学;在小体重方面,对于小体重值和主元素有相关性的矿床,地质统计学法回归方程处理小体重更加合理;在资源储量类别划分方面,地质统计学法以多种参数为依据,自动化划分更加可靠、高效;在其他应用方面,地质统计学法估算结果应用广泛,与生产相结合。因此,地质统计学法明显优于以地质块段法、平行断面法为代表的传统几何法。This article summarizes and analyzes the advantages and disadvantages of the traditional geometric reserve estimation method and the geostatistical reserve estimation method based on the MICROMINE software by comparing three large deposits in four areas. , Compared with the traditional method, the geostatistical method is theoretically more scientific in grade interpolation by variation function. For depos- its in which small block weight correlates with the main elements, the geostatistical method is more rea- sonable to deal with small block weight by regression equation. In resource/reserve classification, the geostatistical method, based on multiple parameters and automatic classification, is more reliable and effe- cient. In other applications, the geostatistical method is more effective especially when combined with pro- duction. Hence, the geostatistical method is much better than the traditional geometric method represen- ted by the geological block method and the parallel section method.
