| 摘 要： | 在矿井生产中,出现交叉断层的区域往往是地质构造非常复杂的地方,也是危险高发的区域。对含交叉断层的3维地质建模的算法进行了研究。其主要思想是分别建立岩层和断层的TIN模型,以断层交线作为约束条件,进行带约束三角剖分,从而建立起交叉断层模型。这将有利于矿山的工程管理,减少危险的发生,作为后续采矿生产的依据。

| Abstract: | In mine production,where crossbedded faults appeared is often the area of greatly complicated geological conformation and danger.This paper researches the algorithm of building 3D geological body containing the cross-bedded faults.The main idea is to: build triangulation irregular net of terrene and faults,regard the intersected lines of terrene and cross-bedded faults as restricted sides,triangulate the areas with these sides,as a result build the cross-bedded fault model.It is advantageous to manage mine projects,reduce danger probability and bring exact data information to subsequent mining production. |
