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 problem that TIN is not easy to be formed in the top and bottom of coal seam under the action of inverse fault, a new method is proposed. This method uses constrained Delaunay triangulation as the theoretical foundation. On the one hand, the TIN can be generated to satisfy the constrained Delaunay principle and the reverse fault to generate TIN can be well solved. The algorithm is easy to implement, stable and reliable, with high efficiency, and is also very helpful to automatically generate contour maps of coal seam top / floor in the future through the inspection of a large number of coal seam normal / reverse faults and multi-period superimposed fault data.
