摘    要:克里格法是地质统计学中最主要和最基本的一种局部估计方法.以某金矿山为例,介绍了在SURPAC软件中应用克立格法进行品位估计应注意的问题及实现步骤:如何进行域的选取,如何进行样品组合,如何进行统计分析,如何做变异函数及进行结构分析,如何利用克立格法进行品位估计及结果的验证等.克立格法利用了脉矿的空间变化及其品位的变化特征来计算样品的加权因素,改变了传统复杂的求体积、体重的储量计算方法,计算矿区储量方便、快捷.

关 键 词:克立格法  地质统计学  SURAPC软件  品位估计  克立格法  SURPAC  软件  应用  Software  Kriging Method  Application  矿区  计算方法  体重  体积  因素  加权  计算样品  变化特征  品位  空间变化  脉矿  验证  结果

Abstract:Kriging method is the most important and basic local estimation method in geostatistics. With a real gold mine as the case, the paper describes the issues needing attention in and the procedures of using Kriging method to estimate the grade in SURPAC software, including how to select the domain, how to make the sample combination, how to make the statistic analysis, how to produce the variogram and use it to make the structural analysis, how to use Kriging method to estimate the grade and to verify the results. Kriging method is used to calculate the weight factor of the samples by using the spatial change of the lode and its grade variation characteristics. Compared to the traditional complex calculation method for reserve volume and weight, it has the advantages of convenience and rapidness in calculating the deposit reserve in SURPAC software.
Keywords:Kriging method   Geostatistics   SURPAC software   Grade estimation
