| Abstract: | Nowadays,3D geological modeling plays an important role in mine planning.It requires building orebody models directly from borehole data in some cases.This paper first introduces general methods of constructing orebody's 3D models and then describes the fundamental principles and workflow of constructing 3D orebody surface models from boreholes.The study shows that the key process of orebody morphological modeling is constructing orebody ellipsoid spheres based on mineral exploring data.Thus,special attenti... |
