The article is devoted to an actual problem of dust control on the roads of mining enterprises. Dust formation on the roads mining leads to air pollution in quarries and performance of enterprises for the reason of a stop of work of technological transport. The assessments of road dustiness in Transbaikal region, made by the author, have showed that the transitional coatings are characterized as heavy dusted. The author has carried out an analysis of the main methods of dust control gravel, sand and soil surfaces. The main dust forming materials: hygroscopic salts, organic binders, polymers, lignosulphonates are described. It is stated that the reduced cost of dedusting technology of roads is possible due to the modification of the main de-dusting formulations of cheaper local materials, by-products and waste production, providing the desired or increased duration. The author has conducted the research on the use of dust in the compositions of fly ash. The two-stage processing technology of the road surface on the basis of emulsion-ash slurry is developed. The technological recommendations are given and the observation results for the state of experimental sections on the roads are presented. The two-stage processing technology allows 2 times to reduce the consumption of bitumen emulsion to increase the period of de-dusting steps to 6-7 months, and reduce dusting surfaces in 4...5 times |
