Abstract: The construction of intelligent mine ventilation is an important content of the construction of intelligent mine. By summarizing and analyzing the existing research on intelligent ventilation technology in mines, the basic theory of intelligent ventilation is deeply discussed, the existing problems and key technologies of intelligent ventilation in mines are clarified, and the key technologies of intelligent ventilation are further innovatively explored. Finally, based on the research of intelligent modules and intelligent systems on the basis of key technologies, a comprehensive mine intelligent ventilation and disaster emergency control system is successfully constructed, which provides a more intelligent and efficient solution for mine ventilation.
