Dynamical modeling of orebody based on property-drive

Traditional orebody modeling was driven by structure conditions. When boundary properties change, the established model was difficult to change dynamically. In order to solve the problem, a dynamic modeling method of orebody based on property-driven was presented. Firstly, 3D block property model was used to extract the required elements in the block model according to any given boundary property conditions. Then, orebody property model was transformed into geometric structure model based on the characteristic face calculation and surface smoothing algorithm. Finally, 3D geometric model of the orebody was established under the given industrial index conditions. The application example shows that the method can extract and generate property structure and geometry structure of orebody dynamically under different boundary conditions, can accurately construct a smooth orebody model and improve the efficiency of dynamic modeling of orebody.
