Orebody Morphological Modeling from Boreholes
摘要
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 attention has been given to the way of obtaining mineral segments and parameters of orebody ellipsoid spheres according to exploration data and experiences. This modeling approach can integrate engineers'concepts of orebodies morphology. Furthermore, a simple case study of an iron deposit is conducted to model the orebodies directly from the three selected boreholes. The model is also compared with the model that derived from contour-based method. The comparison illustrates that modeling from borehole data is more adapted to than modeling based on contours. Finally, some refinements of the method are discussed in the conclusion.关键词
