This subject adopts the site investigation testing, mathematical simulation and calculation method of bining the study. First of all, access to dust diffusion regularity and control related data, onsite survey and site information collection。 Secondly, according to the collected data determine the required technical parameters。 Then, by simulating numerical calculation。 Finally, through calculation and analysis of dust control scheme is put forward.
