摘　　要：最优估值方法以矿床矿化的各向异性为出发点,采用地质统计学方法通过变异函数依据已知样品点对未知点进行品位估值。由于该方法考虑了矿床矿化各向异性的实际,更能真实反映矿床的矿化特征,其估算结果更接近于矿床的真实品位。最优估值方法改变了传统复杂的求体积、体重的储量计算方法。本文通过某铜矿山为例,介绍了在DIMINE软件中应用最优估值方法进行品位估计的实现步骤。Optimal valuation methods,taking depositmineralization anisotropy as the starting point,use geostatisticsvariance function to estimate the unknown sample points grade based on the known sample points.Because thismethod takes into account the actual deposit mineralization anisotropy,which can more truly reflect the mineral deposits,the estimation results are closer to the true grade of deposits.This method has changed the traditional reserve calculation method.In this paper,taken a copper mine as an example,the process of calculating the reserveby optimal valuation methods in the DIMINE software is introduced.
