Research on three-dimensional geological model construction and application of the open pit mine based on sections

Three-dimensional geological modeling (3DGM) is one of key issues to be solved in the three-dimensional geographic information system (3DGIS) and virtual mine technical research. Mine 3D geological modeling and visualization play a very significant role in the process of the mine exporting, designing and developing. Regarding the information of drilling hole and section charts as fundamental data, the author presents a general process of 3D geological modeling based on sections with the utilizing object-oriented programming. The essay builds the three-dimensional geological model in some mine taking the practical project for example and realizes the functions of 3D dynamic display, simulative mining and so on of this mine.
