The environment protection and dust control on washed-in waste piles is complicated by the continuous replenishment of tailings and, consequently, formation of new dusting layer on the pile surface. This problem can be solved using aerosol guns–fogging machines devices within the dust suppression system. The authors propose to place the aerosol dust suppression system on a platform–car moving along a tailings dump. This allows automating dust control and increasing volume of transported water. Grain-size composition of dust at tailing dumps of Kovdor Mining and Processing Plant is determined. From the laboratory experiments, it is found how intensity of dust transfer abates dust suppression. The experimental findings make it possible to calculate the required number of jets for an aerosol gun.
