Abstract:In order to represent 3D spatial entity effectively in geological engineering, layered model for geological mass was put forward based on drill hole information. Firstly, for the given geological drill hole data, adaptive neural network was adopted to forecast ore grade of information unknown areas within the geological sections and then geological layered data was obtained. Secondly, based on discretization meshwork model, topological relations for control points could be established automatically between adjacent data layers, so as to construct surface model of 3D spatial entity, which could be visualized by OpenGL technique. Finally, a 3D simulation system had been developed and some simulation experiments were made with empirical data to analyze the validity of the modeling method. ......
