摘　　要：本文以三道庄钼矿床为例,利用Surpac矿业工程软件,运用地质统计学方法,通过分析三道庄钼矿床钼品位分布规律,进行变异函数计算,建立矿床数学模型。在此基础上运用克立格法进行品位估值和储量计算,再结合传统断面法计算出的储量,将二者进行对比分析,认为采用克立格法计算的矿床储量具有先进性和实用性。With Surpac software,a mathematical model for Sandaozhuang molybdenum deposit was established by applying geostatistics method. Through making an analysis of the molybdenum grade of Sandaozhuang ore body,variation function was calculated via the analysis of statistical distribution features for molybdenum grade. Based on the above,the reserves were calculated by using Kringing method. In combination with the statistics of reserves calculated by the traditional cross section method,and it suggests that the Kriging method for reserves calculation is more advanced and applicable in reserves estimation.
