Description

The relevance of research is due to the widespread intensification of mining processes in the territory of the Irkutsk Region and our country. The issue of assessing the negative impact on the environment is primarily due to the limitations of individual methods, which give only a partial and concise insight into the actual state of violations.
Objective of research: assessment of the dust load on the environment during the operation of mining enterprises.
Objects of research: the largest mining enterprises of the Irkutsk Region, which are of strategic importance for the region in economic terms.
Methods of research: a unique comprehensive assessment of the dust load on the environment. The assessment procedure consists of the primary determination of the causes and sources of dust emissions, followed by the identification of areas of dust distribution during mining and zoning. We performed the assessment of dust distribution areas using the Golden Software Surfer. The next step is the actual procedure for assessing the dust load using several methods. In our case, we used the method for estimating the index of air pollution using dust fraction indicators without gas emissions into the atmosphere, assessing the dust load on the main employees of mining enterprises, and by means of economic assessment of environmental damage.
Results of research: As a result of the atmosphere pollution index estimation, it was established that the total value of pollution from dust was higher than the “average” indicator. We registered a significant distribution of dust particles in areas significantly exceeding the sanitary protection zone. The identified maximum work period under the influence of dust in some cases does not even reach 5 years. As a result of the assessment, we confirmed an indisputable fact - dust pollution is catastrophic and has a negative impact not only through pollution of the atmospheric air by dust particles, but also of nearby territories, polluting water and land resources, disrupting the natural processes of flora and fauna, causing irreversible effects on human health.
