One of the main sources of hazardous air pollution of the territories of mining, metallurgical and enrichment complexes and adjacent areas is the dusty surfaces of bulk dumps. As a result of wind erosion fine fractions, the most dangerous in terms of respiratory hazards, are easily carried away from the surface over long distances. A method ensuring a decrease in dust formation and dust transfer of fine materials, an increase in the bioproductivity of bulk dumps and fast reclamation is proposed. The results of tests of the protective coating for resistance to air flow and the results of bioproductivity of the treated surfaces of the dumps are given.
