Abstract: 3D mine GIS is an important supporting technique for digital mines while the classification and modeling of 3D mine entities are the basis for 3D mine visualization and management. The paper first classifies 3D mine entities into static and dynamic ones according to their states in mine production process; then proposes to use extended-surface modeling for the static entity set and voxel modeling for the dynamic entity set; and  finally describes the integrated management and visualization methods for these two types of entities in 3D space. The feasibility of the proposed methods is verified by a case study of a metallic mine in Hunan.

Key words: 3D Mine, 3D data model, Static entities, Dynamic entities, Mosaic model
