为了实现矿井通风管理的信息化和自动化,基于三维地理信息系统(GIS)技术,构建了矿井通风系统图的三维数据模型和几何模型,利用OpenGL中的拾取机,以ADO作为数据库引擎,开发了三维GIS矿井通风信息系统,实现了矿井通风系统的三维可视化建模和风流模拟,并可对巷道属性和通风属性进行动态交互式查询.系统的开发对提高矿井通风的管理效率具有很大的作用,增强矿井生产的安全性,提高煤矿生产的经济效益,具有较强的应用前景.
In order to realize the informationization and automation of mine ventilation management, based on the three-dimensional geographic information system (GIS) technology, a three-dimensional data model and geometric model of mine ventilation system are constructed. By using the pick-up in OpenGL and ADO as the database engine, The three-dimensional GIS mine ventilation information system realizes the three-dimensional visual modeling and airflow simulation of the mine ventilation system, and can dynamically and interactively query the properties of the tunnel and the ventilation properties. The development of the system plays a very important role in improving the management efficiency of mine ventilation , Enhance the safety of mine production and improve the economic benefits of coal production, with strong application prospects.
