Abstract: Basic concept and features of augmented reality technology were introduced, idea of applying augmented reality technology to mine ventilation system was proposed combining with development trend of smart mines in China. Application prospect of augmented reality technology in mine ventilation system was analyzed from three aspects, namely 3D visualization of data model, orientation recognition and guidance and realistic enhancement of ventilation tunnel. The analysis results show that using augmented reality technology can realize visualization of the ventilation tunnel data, and obtain real-time information of roadway environment, orientation recognition and guidance are more precise and humanized, which provides a new technical means for intelligent management of mine ventilation system.
