矿体数据的存储数据结构及实践

Data Storage Structure of Mining Layer and Its Application

将扩展的数据库管理系统EDBMS(Extend Database Management System)和八叉树数据结构相结合,实现对矿体空间数据及相应属性数据的存储结构—NRDM(Nested RelationData Model)。在此基础上,实现了矿体的计算机模拟可视化,并能进行数据操作及图形的编辑。最后,用实例验证了文中所述数据结构的正确性。

The data structure of underground mining layer has been designed by the EDBMS (Extend Database Management System) and OCTREE data structure. And the data structure is named NRDM (Nested Relation Data Model). Base on the NRDM, underground mining layers have been viewed. The data can be operated and the graphics can also be edited. At the end of the paper, a real application example is given.
