摘要:

最近距离插值法简称最近距离法,是一种相对简单的空间差值方法,在目前流行的地质资源估算软件中都提供这方面的功能。但是最近距离法因为其固定的缺点,在资源估算实践中并不常用。圈定矿体或岩相域在传统地质建模中一般使用手工圈定,这项工作一般为地质建模和资源估算工作中耗时最长的一个步骤。本文结合南非某大型铂矿项目,探讨使用最近距离法来实现自动圈定岩相域边界,提高工作精度和效率,文中以使用Datamine Studio 软件为例,介绍具体建模步骤,并应用到实际项目,获得了良好效果。

关键词: 地质建模, 最近距离插值法, Datamine软件, 铂矿, 南非

Abstract:

The Nearest Neighbor Method(NN) is a simple spatial interpolation method,and the functionality is provided in the currently popular resource estimation software.As NN has the unique disadvantage,it is not commonly used in the practice of resource estimates.Delineation of ore and lithofacies domain generally used traditional geological modeling-manual mode,it is the longest step in resource estimation process.Combined with the project of a Layered platinum ore in South Africa,we have studied that using NN delineates ore and lithofacies domain boundaries with Datamine Studio software automatically,to get higher accuracy and work efficiency.We introduce the modeling process of Datamine Studio software,and applied it in the practical project,and have achieved satisfactory effects.

Key words: geological modeling, Nearest Neighbor, Datamine, platinum mine, South African
