【Abstract】 It is significant to introduce 3D GIS,3D geological modeling and visualization into solid mineral resource estimation to improve intelligentization,automation and work efficiency of resource estimation.a new approach and efficient methods of solid mineral resource estimation is presented using 3D geological modeling and visualization.An optimal solution to reconstruct orebodies’ pinch-out zones and branches is also proposed using the algorithm of 3D surface reconstruction from 2D contours.During the modeling process,it is allowed to control models’ reconstruction on the basis of experience,knowledge and interpretation of geological structures and geophysical data.更多还原
