本文以加拿大某斑岩型铜钼矿体为例,介绍了地质统计技术的现场实施过程。该矿体高品位带集中在矿体核心部位,其平面尺寸约为3000×2500英尺,向下延伸到原地表以下至少1000英尺。目前,3号露天采场开采的是临界品位矿石,随者采坑的加深,开采将向高品位的核心部份推进。以往使用的(?)文件,(MIF)是可行性研究期间采用影响半径法编制的,岩心孔之间矿石的品位(?)距离平方反比加权法计算。

In this paper, a porphyry copper-molybdenum orebody in Canada is taken as an example to introduce the field implementation of geostatistical techniques. The ore body high-grade belt concentrated in the core of the ore body, the plane size of about 3000 × 2500 feet, extending down to less than 1000 feet below the original surface. Currently, No. 3 open pit mining is the critical grade ore, with the deepening of mining pit, mining will be to the core of high quality promotion. The previously used (?) Document, (MIF), was calculated using the influence radius method during the feasibility study and the grade ()) of the ore between the core holes inversely proportional to the square of the inverse square method.
