Ore reserve estimation and classification is of very impordance in geological prospecting.In conventional methods ore reserves are qualitati vely classified by some generalized terms, while in geostatistics (various Kriging methods) not noly the average grade of estimated blocks , but also the estimated accuracy (Kriging variance) are given. For quantitative classificati on of ore reserves, geostatistical methods are the best. This paper deals with the characters of Kriging variance and its influention factors in detail. In addition, problems of economic feasibility, geological reliability recovery and those factors having a great effect on geological reliability, such as the size of the blocks to be estimated, the distance between drilling holes, structure characters of an orebody, cutoff grede, etc., are also discussed. At the end of the paper, some useful geostatistical criteria of ore reserve classification,tbe calcul ating method and computor program together with a practical example for an iron deposit are given.

矿石储量计算及其分级是地质勘探工作中最后而又最重要的成果,传统的矿石储量分级一般是定性的,即用一些概念化的术语来刻划矿石级别。地质统计学(克立格法)不但给出待估块段的平均品位,而且还给出了估计的精度——克立格方差,因此,地质统计学是定量化矿石分级的较好方法。作者详细地研究了克立格方差的性质及其影响因素,讨论了关于经济可行性、地质可信度及可回采率的有关问题,特别讨论了影响地质可信度的若干因素,如待估块段的大小、孔距、矿体的结构特征以及边界品位等。最后,给出矿石储量分级的地质统计学准则、计算方法及程序系统和对一个铁矿床的研究实例。

In conventional methods, ore reserves are qualitatively classified in some generalized terms, while in geostatistics not only the grade of estimated blocks, but also the estimated Kriging variance are given. Geostatistical methods are practicable for the quantitative classification of ore reserves. This paper provides a geostatistical criteria of ore reserve classification. At the end of the paper, a practical example of ore reserve classification for Chengmenshang Copper Mine is given.

传统的矿石储量分级是以概念化的术语描述进行定性分级;而克立格法不但给出了待估块的品位,并且给出了估计方基,因此,应用克立格法进行矿石储量分级是一种可行的定量分级方法.本文给出了基于克立格法的矿石储量定量分级判据以及江西城门山铜矿储量分级的研究实例.
