Abstract:

Three-dimensional geological modeling has become an important means of geological inter⁃

face morphology description and deep metallogenic prediction. It is of great significance to improve the effi⁃

ciency and accuracy of modeling.Based on the section modeling system，taking a copper-zinc mine in Tibet

as an example，this paper introduces the geological data needed to construct the vein ore body model based

on the mining engineering software 3Dmine combined with Auto CAD，and the method of constructing a

large number of sections from two-dimensional to three-dimensional ore body model.The practice shows that

the method overcomes the problems of complicated and time-consuming work of 2D to 3D conversion of a

large number of profiles manually.Using two kinds of software to construct the ore body can improve the mod⁃

eling efficiency，and the modeling accuracy is high.
