Abstract: It used VC++ and OpenGL as the main development tools for studying roadway, ventilation structures and mine ventilation power plant. Delaunay was used for roadway modeling researching, and roadway interchange ofmodeling and algorithm are also researched in this paper，meanwhile first proposed that texture image is used for researching ventilation structures and mine ventilation power plant.

Key words: OpenGL , Mine ventilation system , Tunnel modeling , Visualization

摘要：     　以面向对象的程序开发语言Ｖｉｓｕａｌ　Ｃ＋ ＋和三维图形应用程序接口ＯｐｅｎＧＬ为主要开发工具，对构成通风系统的巷道、通风构筑物、矿井通风动力装置进行了可视化研究。采用网格技术中的Ｄｅｌａｕｎｅｙ三角剖分算法对巷道的建模进行研究，并对巷道交汇处的建模和算法进行了分析，同时创新地提出了用图像纹理映射的方法对构筑物和通风装置进行可视化研究。
