Application of 3-D Geoscience Modeling Technology for the Estimation of Solid Mineral Reserves

P5; 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 resfrves,and implementing dynamic estimations of reserves.
