DUST FALLING APPARATUS BY MEANS OF WIND AND WATER

The utility model discloses a dust falling device by means of wind and water, mainly used for falling coalmine dust. After the pressure wind and pressure water used in drilling are mixed in a wind-water mixing chamber (6) and become mixture of wind and water, the dust falling device spurts a strong solid fog flow with high pressure towards a dust zone; the range reaches to more than 15 metres and the diameter of the fog flow reaches about 4 metres. By testing, after dust fell by the dust falling device, the dust concentration of working faces is reduced to less than 2 mg/m+[3] which reaches to the national dust falling standard, and investment is saved.
