| 摘 要： | 脉状金矿体空间形态的估计误差对矿床储量的影响远大于矿块品位的影响，提出指示值作为区分矿与非矿的指标，并且指出这种指标具有区域化变量的特征，可以利用克立格法对其进行有效估计，进而确定矿体的空间形态，通过研究认为此法可作为一种精确估计矿床储量的有效途径。

| Abstract: | As the estimated error of spatial shape of the vein will in fluence the accuration of the reserves more than the block grade .During computing the reserves of a vein type gold deposit,the paper proposed that indicator is a very useful tools to seperate ore and waste in deposit,and can be cosidered as a regionalied variable.The block estimation by Kriging can outline the special shape of the orebody.The study shows that this is a available way to accurately estimate the reserves of the vein type deposite. |
