In carrying out mass explosions in quarries, a considerable amount of dust and gases is emitted into the atmosphere, more than in other technological processes of mining. The dusty cloud formed during the explosion pollutes the atmosphere not only of quarries and their industrial sites, but also the territory adjacent to them. However, the known methods and measures to reduce dust and gas emissions into the atmosphere during mass explosions have not solved this problem yet. In addition, the implementation of most methods involves certain financial costs. Therefore, the development of new ways to moisten career blocks with solutions of modern reagents produced in Ukraine is necessary and relevant. Considering the increase in the depth of quarries and, as a consequence, the extension of the length of quarry roads, the authors proved that these factors lead to an increase in the amount of dust formation from the road surface. In this regard, the solution of the problem of reducing the dust generation on the quarry roads is an important and relevant. This work is devoted to an experimental study of the determination of the effectiveness of the use of an aqueous solution of the surfactant "Leksol" to reduce dust emission during mass explosions and dust binding on the quarry roads. The problem is solved by means of industrial research to determine the effectiveness of reducing dust formation during mass explosions by pre-wetting quarry blocks with aqueous surfactant "Leksol" and binding dust on quarry roads during their watering with proposed aqueous reagent solution. The studies have confirmed the process of binding with surfactant "Leksol" of fine dust particles remaining on the surface of the quarry block after drilling on the surface thereof, and are actively involved in the overall process of formation of dust and gas cloud. At the concentration of the aqueous solution of the anti-dust reagent "Lexol-5" 5%, the average efficiency of dust suppression was 21%.
