For the precise quantification and calculation of solid mineral resources and reserves, this study utilizes data from exploration projects, mining design, and engineering surveys during the exploration and development of solid minerals. By employing three-dimensional (3D) digitalization methods and visualization techniques, we have constructed 3D geological attribute models, designed mine-out models, and 3D excavation engineering models. Furthermore, we have integrated the statistical computation of resources and reserves with these 3D entity models, proposing a 3D statistical computation method and data management framework specifically tailored for solid mineral resources and reserves. The findings indicate that the application of 3D digitalization methods enables accurate and detailed accounting and computation of resources and reserves and production ores, precise classification of resource reserve types, and dynamic updating of resources and reserves based on the continuously expanding information of ore body control points, thereby enhancing the efficiency of dynamic management of solid mineral resources and reserves. Practical application cases have further confirmed the feasibility and effectiveness of the 3D digital dynamic management method for solid mineral resources and reserves.
