In order to study the dust fall effect of magnetized water spraying on the fine dusts in the coal mining face and the gateway driving face,an experiment was applied to measure the surface tension and dynamic viscosity of the water after magnetized treated by the new type water magnetizer and the wettability of the fine dust,and a similar model of the driving gateway was established. The dust fall effect of the magnetized water under different parameters was studied. The results showed that the surface tension and dynamic viscosity of the water after the magnetized treatment were all reduced. More close distance of the water magnetizer to the water outlet,the higher surface tension and the dynamic viscosity of the magnetized water would be reduced and the higher magnetized effect would be. The wettability of the fine dust with the magnetized water would be better than the non-magnetized water and the dust fall rate could also improve than the non-magnetized water. Experiment results showed that,the conditions of magnetic induction strength 170 mT and water pressure 2 MPa would be the optimized condition for dust fall with the magnetized water and the dust fall rate improved by 16. 36% than non-magnetized water.
