Abstract
The study of the biochemical status of the population revealed a decrease in the antiradical activity and inhibition of the oxidase activity. The dynamics of glutathione reductase activity was established, which is a consequence of metal-induced intoxication. Indicators of the health status of the population of mining areas correlate with the number of pollutants entering the environment and the size of the contaminated area. The advances development of metal-induced oxidative stress was established, which reduces the quality and duration of human life. The health of the inhabitants of the mining region and the loss of metals during the extraction of ores depend on the share of dust and fine ore fractions, which, during enrichment end up in waste and are carried by water and wind. It is shown that the minimization of chemical pollution of the environment with metals is possible with the use of technologies that limit the contact of ores with the environmental ecosystems. At the same time, aggressive small fractions do not enter the habitat, and the extraction efficiency increases due to the recovery of the previously lost metals. The technology of leaching metals in the underground blocks was industrially used for more than half a century ensuring in some cases a large share of the production capacity of the enterprises. Leaching in the disintegrators passed the stage of laboratory research on the Sadon polymetallic ores and ferruginous quartzites of the Lebedinskoye deposit. The results of study of the quality of mined ores use, including the effect of dust and fine ore fractions on the health of the population are consistent with the conclusions of the researchers. It is concluded that there is a correlation between the health of residents of residential areas and the quality of mined ores use. Therefore, expanding the scope of metal leaching technologies is the key in solving the problems of rational use of subsoil resources and ensuring the safety of workers.
