Abstract. Great attention is paid worldwide to the ecology and ecological characteristics of the environment. Environmental safety is controlled in the mining regions and near the mining enterprises. To reduce dust emissions during single blasting in open pits, modern methods of dust control are used and new types of impulse explosives are applied. However, a problem of air pollution within the neighbouring territories is only being deteriorating. With this object in mind, more than 30 000 stations of air quality monitoring have been built all over the world. They record the indices of gases and fine-dispersed dust particles PM 2.5 and PM 10, which are the main factors of chronic disease risks.
The paper objective is to evaluate the nature of changes in air dustiness at the territory of mining Kryvyi Rih region taking into account the effect of single blasting in the open pits, meteorological conditions, and exogenous factors.
The paper represents the analysis of single blasting influence on the dust particle concentration in the atmosphere. The analysis involved both meteorological data and the data on the air quality obtained from 10 stations of automatic monitoring at the territory of the Kryvyi Rih region. Basing on the obtained data, graphs of temperature change, wind velocity and direction, relative air humidity, and dust particle concentration were developed. Interrelations between the meteorological conditions and dust particle concentration in the air were studied. It was identified that within the observation period single blasts in the open pits did not affect considerably the atmospheric dust pollution in the Kryvyi Rih region. The influences of the temperature inversion in dust concentration at night time were analyzed. It was specified that high temperature inversion was observed within the considered period of time.         
Keywords: ecology, monitoring stations, dust concentration, fine-dispersed particles, single blast, open pit.
