摘要: 矿山三维GIS是数字矿山重要的支撑技术,而矿山三维实体的分类和建模是矿山三维可视化与管理的基础。首先对矿山三维实体进行了分类,并根据矿山三维实体在生产过程中赋存状态,将其分为静态实体集和动态实体集;接着,提出扩展的表面模型实现静态实体集的建模,使用体元模型实现动态实体集建模;然后,描述了两类实体集的在三维空间中整合管理与显示的方法;最后,以湖南某金属矿山为例,验证了所提方法的可行性。

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.
