Using the example of Open Joint Stock Company «Pavlovskgranit», located in the Voronezh region, the level of impact of technogenic factors (air pollution and noise) during the extraction and production of crushed granite was estimated. It was established that 61 pollutants enter the atmospheric air from 134 sources of pollution. The main contribution to the total volume of emissions (1881.0 tons/year) is made by inorganic dust with a SiO2 content of 70-20% - 73.4%, sulfur dioxide - 9.8%, carbon monoxide - 114.3 tons/year. Blasting operations in open pits during the extraction of crushed granite are the leading production process that makes a significant contribution to the volume of emissions. At the same time, the remoteness of industrial sites from the territory of residential development, the presence of a sanitary protection zone, allows us to speak about the admissibility of the impact of concentrations of pollutants in the air and the noise factor at the border of the territory of the nearest residential development.
