Modeling technology of 3D visualization orebody based on solid and block model
Abstract：The integration model that contains the external contour and internal quality of orebody built on the computer,is the principal problem to be solved in the information management of mine and three-dimensional calculation of reserves.The basic principles and methods constructing orebody visualization modeling under three-dimensional environment according to the geological interpretation of boundary lines was studied.Due to the inefficiency of traditional modeling methods and complication of procedures implementation,the algorithm to build volume element surface triangulation out of geometric proportion within the line length was put forward,and key algorithm of block quality formation under the constraint of volume element model was studied.The rapid filling algorithm of three-dimensional block model based on BSP tree structure is suitable for large-magnitude block formation constrained by complex orebody,and was successfully applied to many digital mine projects.
