摘要
The three-dimensional model is not only based on digital mine,but also the digital representation of deposit.First,it builds the geological database using the drill data which extract from geological maps,topographic maps,geological cross-sectional view and bore histogram,including the Sampling information,the drilling form and the drilling location,then demonstrates the drill holes in 3D view.Second,after the process of profile definition,delineation of geologic body(ore body,fault,alteration zone,the outdoor layer) in a single drill hole,edition of profiles,connection of surfaces,encapsulation of surfaces based on Minexplorer software,it builds the geologic body in three dimensions,finally realization of the 3D visualization of the geologic body.It calculates the reserve of ore body by the section method,the block method,and the distance weighting method.The results are compared with the real reserve by the production of the mine.The results show that in the calculation of inverse distance weighted method there is minimum relative error,which in turn,verifies the accuracy of the 3D geologic body model.
