A mine ventilating device with temperature and humidity regulating functions comprises a supporting system and a ventilating system. The mine ventilating device is characterized in that the supportingsystem comprises a base (1) and idler wheels (2) arranged on the lower portion of the base (1), a water spraying circular power device is arranged in the base (1), and a storage battery (6) is further arranged in the base (1); the ventilating system comprises a ventilating pipe (9), an air outlet position of the ventilating pipe (9) is connected to one side of an air inlet (10), and an air bellow(12) is arranged on the other side of the air inlet (10); a water stop device (14) is arranged at the air outlet position of the air bellow, a temperature adjusting device is arranged in the water stop device (14), and a spraying chamber (15) is formed in the other side of the water stop device; and an air outlet (16) is formed in the air outlet position of the spraying chamber (15), and a baffle(17) is arranged outside the air outlet (16). According to the mine ventilating device with the temperature and humidity regulating functions, by changing the humidity and temperature of an air flowsucked into a mine, the operation environment of the mine is greatly improved.
