基于3D MAX的矿体三维立体形态研究

以小西南岔铜金矿北山矿段ⅠⅡ号脉系金、铜矿体为例,提出按品位分级的研究方法,探讨其形态特征和空间赋存规律,进而将矿体细分为矿饼微元,由此建立北山矿段金、铜矿体的三维立体形态模型。从而得出如下结论:(1)使用3D MAX软件将矿体形态可视化,方法简单易行,便于指导矿山管理、设计和生产;(2)提出品位分级形态的概念,有利于人们更好地认识矿体在空间的展布形态和分布规律,为解决矿体随时间等因素变化提出了一种新的研究思路;(3)对分段富集规律有了新的认识,将其应用范围从平面域扩展到空间领域,进而更好地预测隐伏矿体。

Study on 3D Spatial Shape of Ore Bodies Based on 3D MAX

The authors introduce the method of 3D MAX software to model the ore body,note the construction of the geological curved surface,as well as the principle and process with the 3D MAX software.Taking I-II copper-gold veins in northern field of Xiaoxinancha copper-gold deposit as an example,authers discuss their shape characteristics and the depositing rules,with new method of the shape on the grade of content.Further more,the ore body is subdivided into ore cakes and the 3D model of the copper and gold ore bodies in north field are founded.Such conclusions have been drawn as followings:(1) The method of 3D MAX software proves to be very simple and easy and available for mine management,design and production.(2)The proposed concept of the shape on the grade of content is advantageous to describe well the ore body,the shape and the distribution rule in the space.It also gives one new research mentality along with the invariable factors,such as the time,the price,and so on.(3) New understand about the law of partial concentration have been got.Its use is expanded from the plane territory to the spatial scope,as to forecast the concealed ore body freely.
