三维地质建模已经成为地质界面形态描述和深部成矿预测的重要手段，提升建模的高
效性和准确性意义重大。立足于剖面建模体系，以西藏某铜锌矿为例，介绍了基于矿业工程软件
3Dmine联合Auto CAD构建脉状矿体模型所需的地质资料，以及大量剖面由二维快速转换到三维的
矿体模型构建方法。实践表明，方法克服了人工对大量剖面进行二维到三维转换的工作繁杂、耗时
长等问题；利用2种软件联合构建矿体可以提高建模效率，且建模精度较高。
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.
