Abstract: Mine mine ventilation system is an important part of the production system and it is basic condition to guarantee the mine safety production.The optimization intelligent ventilation system is constructed,so as to clear the ventilation paremeters automatically and realize the on-line monitor the wind speed,air volume,air pressure,the gas,dust and harmful gas and conduct the mine's reversing wind exercise at the base of constructing the three-dimensional mine ventilation model.The research results indicate that,the optimization intelligent ventilation is good for improving the mine safety production,preventing and controlling the mine gas ,coal dust and fire.

Key words: Mine Ventilation, Intelligent optimization, 3D digitalization, Function
