Abstract: In order to improve the dust control effect in heading face, the ventilation duct with Coanda effect is used in the way of far-pressing-near-absorption ventilation. In order to improve the effect of the dust control, in this paper, CFD is used to simulate the distribution of frontal airflow and dust space before and after joining ventilation duct with Coanda effect （VDCE）, and measured data are verified. The results indicate that the wind speed in most areas of the head is reduced to less than 1 m/s from 5 to 10 m/s by using the cyclone and air splitting effect of the VDCE, the flow field distribution is more uniform and stable without vortex. At the same time, the air curtain appeared in front of the driver can block high concentration of dust in the head of 5 m, which increases dust collection and purification efficiency of spray and dust removal fan. The measured data showed that the dust rate of the driver increased by 13%.
