Mining enterprises the Republic of Buryatia: impact on atmospheric air and environmental risks

The research topic reveals the relationship between the scale of mining and the environmental consequences for the region. On the example of the Republic of Buryatia, the activity of mining facilities was studied, the state of the ecosystem under the intense impact of coal and gold mining was analyzed. The purpose of the study is to present a comparative assessment of environmental risks growing against the background of the activities of mining companies on the territory of the Republic of Buryatia. In the region, there is a problem of pollution of coastal waters, river basins, aquifers during mining or as a result of pollution in mine waters from facilities that have ceased operations for one reason or another. The authors found that for the period from 2019 to 2021, on average, 3 environmental emergencies related to the withdrawal of mineral resources occurred annually on the territory of the republic. The paper proposed an algorithm for monitoring and assessing atmospheric air pollution through comparisons of average concentrations of pollutants. Using the statistical method, an analysis of the production, control of enterprises was carried out, and using the method of determining the atmospheric pollution index (ISA), in assessment of the level of atmospheric pollution by similar ecostressors as part of the emissions of enterprises was carried out. According to the results of the calculation, it was found that the Okino-Klyuchevskoye field and the Irokinda mine have the highest indicators among their group of enterprises by the type of raw materials extracted, which means they cause the highest harm to the state of atmospheric air. A comparative assessment of the ISO allowed us to conclude about the slightly polluted state of the air basin.

Keywords: mining enterprises, ecological risks, ecostressors, air pollution index, Republic of Buryatia, dust, ranking of enterprises, gold mining, coal.
