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。

Abstract: In order to solve the difficulty of coal seam TIN dealing with reverse faults,a new algorithm of con-strained 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.
