基于钻孔数据的三维地质建模及可视化系统3DGMS的设计与实现

Design and implementation of 3D geological modeling and visualization system (3DGMS) based on borehole data

矿山三维地质建模及可视化是实施数字矿山战略的关键技术,其软件系统的研究与实现对于矿山企业的可持续发展具有极其重要的意义.基于OpenGL图形库和VC++6.0开发平台,从系统目标要求、体系结构和功能模块等几方面设计和开发了基于钻孔数据的三维地质建模及可视化系统3DGMS,实现了地层、矿体、断层、地表和巷道等三维模型的创建与可视化显示,以及灵活的三维视图控制和针对地质模型基本的空间查询、量算、空间剖切、动态模拟等空间分析功能,为我国矿山三维地质建模及可视化软件的设计提供了参考,有益于促进我国矿山信息化的建设.

3D geological modeling and visualization of mines are the key technologies to implement digital mining strategy. And the study and realization of software system has extremely important realistic meanings to mining enterprises sustainable development. Based on OpenGL library, a 3D geological modeling and visualization system is designed and developed from system target, structure and function with VC＋＋6.0. The 3D modeling and visualization of strata, ore body, fault, terrain, roadway, and etc are realized. And the 3D view control and some spatial analysis functions such as query, measurement, sectioning, dynamic simulation and so on also are realized. The paper provides reference for design of 3D geological modeling and visualization software, and promotes the informatization construction in mine.
