Abstract
The article presents the results of studying the dust generated as a result of large-scale blasting in a coal strip mine. Its element composition has been studied, and the results of sieve analysis of dust have been provided. Justification for the location of the dust collection units is given based on the empirical dependence.
Keywords
Monitoring, Dust content, Particle size distribution, Elemental composition, Windrose diagram, Microscopy method.
