Moscow Lignite Basin’s Waste Dumps as a Source of Dust Emission

Abstract

There were bringing results of summarizing field observations of the processes of dust formation on the waste dumps abandoned mines in Tula Region. There was shown that dusting intensity of waste dumps depends on particle size distribution, humidity of dust, wind direction and speed. There was found that еру majority of abandoned mines excess MPC of heavy metals in soils kin the dumps coverage area is not observed, with the exception of lead, exceeding the concentration of which is 8 MPC. Dust emissions pollute the atmosphere and lead to contamination of soils adjacent to the dump.
