摘　　要：为了解决逆断层参与下煤层顶底板不易生成TIN的问题,提出了一种新方法。该方法以约束Delaunay三角剖分为理论基础,一方面使生成TIN满足约束Delaunay原则,另一方面又很好地解决了逆断层生成TIN的问题。通过大量煤层正/逆断层和多期叠加断层数据的检验,该算法容易实现,稳定可靠,效率高,并对将来自动生成煤层顶/底板等高线图也很有帮助。In order to solve the difficulty of coal seam TIN dealing with reverse faults, a new algorithm of constrained Delaunay triangulation is proposed. The TIN built by the algorithm, on the one hand meets constrained Delaunay principle, and on the other hand is a good solution for formation of TIN of reverse faults. The algorithm, checked by various coal geological data with complex normal/reverse faults and fault combination, is simple, high-efficient, and useful for automatic creation of coal roof/floor contour map in the future.
