Abstract: Considering the current status of the visualization of mine ventilation system in China, we design a mine ventilation visualization system with easy operation and high sharing. The development of the system is based on Windows system as platform, Access as back-end database, database system as B/S (Brower/Server) model, which combines the results of ventilating network and mine ventilation graphic. The visual system can reflect the status of mine ventilation accurately, intuitively and comprehensively which optimizes the mine ventilation management and improves the ventilation efficiency.
