Microparticles variations concentration during the mass explosions at the Lebedinsky quarry

Abstract

Instrumental observations of the dust and gas clouds development and microparticles emissions into the atmosphere were carried out during mass explosions at the Lebedinsky quarry. In the process of observations, a stationary observation point and a number of mobile points were organized. The results of observations made it possible to obtain estimates of both the maximum values of the solid particles concentrations and their average daily values in the settlements located in the immediate vicinity of the quarry. Sources of particulate matter emissions not related to technological operations at the quarry were also identified.
