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。In mine production, where cross-bedded 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 crossbedded fault model. It is advantageous to manage mine projects, reduce danger probability and bring exact data information to subsequent mining production.
