摘要:Based on the theory of coupling discrete phase model, air flow regularities and dust distribution were investigated by using CFD, contrastive research on dust concentration was carried out under different factors, such as different coal seam dip angle, different ventilation quantity and different dust diameter, and comparative analysis between simulating dust concentration and field measurement results was conducted. The results showed that air trends to flow near coal wall in high inclination-angle fully mechanized caving face. The respirable dust is active with adding coal seam dip angle. After appropriate increase air volume, respiratory dust is easy to be carried by air, and the dust concentration reduces obviously, but too large air speed may produce secondary dust.
