This paper presents the basic principle and the evalu- ation model of gray correlation analysis, determines evaluation indexes of mine ventilation system, then applies gray correlation analysis to select optimizing and reforming scheme of a mine ventilation system. The result shows that the method can objectively determine optimal scheme of mine ventilation system, and has greater applied value.
