摘要
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.
