Abstract
Abstract:Applying new approaches, methods, and technologies for the estimation of reserves can effectively improve the efficiency and accuracy of assessments of solid mineral resources. After analyzing the development of 3‐D geoscience modeling technology (3‐D GMT), this paper discusses the application of 3‐D GMT for the estimation of solid mineral reserves, emphatically introducing its workflow and two key technologies, 3‐D orebody surface modeling, and property modeling. Moreover, the paper analyzes the limitations of traditional methods, such as the section method and geological block method, and points out the advantages of 3‐D GMT: building more accurate 3‐D orebody models, expressing the internal inhomogeneous attributes of an orebody, reducing the potential for errors in the estimation of reserves, and implementing dynamic estimations of reserves.
