Mining Subsidence Prediction Based on 3D Stratigraphic Model and Visualization

摘要

3D phenomenon involved ia mining subsidence was C.assified, summanzed and aggregated, established the hierarchical structure that describing the geologic phenomena and engineering phenomena of stratum structure Proposed a 3D stratigraphic model that mixed Multi DEM with Tetrahedral Network. The model uses Multi-OEM to build layered su-face of the earthis surface and geology, and uses TEN to makeup inter .ayer geological mass. This is in favor of exactly expressing the surface information, and it is benefit to engineers and technicians to check the geological condition in the stratum, also it provides detai'ed geological mining conditions for the mining subsidence prediction research anc accurately establishes prediction model. Englneering sample shows that the predicted results of the system is more close to the measured values.
