摘　　要：在矿山生产实际中,准确估计矿体品位空间分布规律和总体储量有利于提高矿山生产效率,降低生产成本。文章采用对数克立格(Log Kriging)法和距离反比法以个旧锡矿芦塘坝10-9号矿体为研究对象计算储量,其结果分别与地质块段法计算的储量进行了对比,并探讨了前两种计算方法的影响因素及其产生误差的根本原因。Accurate estimation of dimensional distribution regulation for ore body grade and calculation of total reserves have an advantage to improving production efficiency and lowing production cost in the actual mine production. Log Kriging and reverses distance weighting methods are adopted to calculate reserves for No. 10 -9 ore body of Lutangba mine in the Gejiu tin deposit. Calculated reserves by Kriging are compared with that by geological block method. Influence factors and reason of producing errors by these two methods are discussed.
