    • Abstract
  • In order to enhance the effect of dust control at fully mechanized excavating face, radial outlet angle of fresh air for wall-attached wind tube is studied. Fluent is used to simulate the influence of different angle on dust control effect; wall-attached wind tubes under different radial outlet angles are selected to apply for practice.The results show that different radial angle of the wind has a different inflence on dust control effect; when the radial angle of the wind tube is 0 °, secondary pollution is caused by transport belts; so the best dust control radial angle is 15 ° or 30 °.
