地质统计方法是建立在矿床地质特征、勘探方案和储量计算精度三者之间严格的数学关系基础之上的一种数学地质方法。据此,不仅可以利用它进行储量计算,而且可以用它来研究矿床的最佳勘探方案——网型和网度。目前我国对于勘探工程最佳数量,勘探网最佳布置形式的研究,通常多依靠矿床勘探的经验,根据被勘探对象的规模,形态等来确定。这样做往往忽略了勘探成本与估值精度之间的正确关系,从而造成一些不应有的经济损失。本文是笔者对吉林省九台银矿山膨润土矿床1号矿体,使用地质统计方法,评价和预报勘探网型和网度的一个实例,现将我们的体会作一介绍:
Geostatistical methods are a mathematical geologic method based on a rigorous mathematical relationship between the geological features of the deposit, the options for exploration and the accuracy of reserves. Accordingly, not only can it be used for reserve calculations, but it can also be used to study the best exploration program for the deposit - the mesh type and the mesh size. At present, the research on the optimal number of exploration projects and the optimal arrangement of exploration network in our country depends on the experience of prospecting and the determination of the optimum according to the size and shape of the exploration target. Doing so often neglects the correct relationship between exploration costs and valuation accuracy, resulting in some unnecessary economic losses. This article is the author of Jilin Province Jiutai silver mine bentonite deposit No. 1 ore body, the use of geological statistics, evaluation and forecasting of exploration network and network of an example, now we make an introduction:
