Research on 3D Simulation Modeling Method of Faults Based on Coal Stratum Floor TIN
Keywords:three-dimensional fault modeling, three-dimensional interactive, coal stratum floor, triangulated irregular network (TIN), contours
The research on 3D simulation technology for complex geological body according to geological and remote sensing data is a hot issue in current geosciences research field. The simulation and expression of coal mine structures containing faults are the main bottleneck. A new 3D interactive simulation modeling method is proposed and a relevant code is developed for the method. By using the system, the fault data can be gained from the coal stratum floor triangulated irregular network (TIN) interactively, and the 3D solid models of the fault are generated according to the results of computing the fault/coal seam intersection line, fault modeling centre lines and fault modeling influence domains. Moreover, the floor contours of coal stratum including faults can be updated quickly and accurately, which lay the foundation for precise modeling of coal body and digital mine construction.
