Abstract


The 3D geological models of the open pits can express the current features and the characteristics of the formation information and the structure of the geologic bodies, which is of great significance for the design and the decision about the surface mining. Therefore, the developing-technology of the 3D geological models of the open pits is a preceding and hotspot problem in the field of mines.In this thesis, the developing methods and interpolation methods of the digital elevation models, then, based on the terrain feature, the deposit character and the exploitation status of Heidaigou Surface Mine, the facial model of the land surface, the deposit interface model and the interface model of the open pit. The previous harvest was summarized, then a method to develop the 3D solid model of the coal and rock mass based on the geologic sections and the solid model the current open pit was generated by extending the plane domains. The developed model was applied to cut the cross sections, calculate the geological reserves and the scheming quantity and generate the contour map, which gained a good result.
