Metal Ore Mining Technologies and Health of the Mining Region Population


Annotation:

The issues of preventing chemical exposure of the products of mining and processing of mineral raw materials on the population of mining facilities are considered.
The results are presented concerning assessment of the correlation between the intensity of chemical pollution of the infrastructure of mining enterprises and the health of miners and the population living in the vicinity of a mining enterprise by means of clinical and biochemical examination of residents. It is established that the negative effect of mining production on the health of the population is a consequence of development technologies with the abandonment of untreated ores in the cavities, where physicochemical processes of natural leaching are developing. It is shown that the known methods of fixing dumps reduce only the parameters of dust pollution without effecting the contamination of the territory with metal solutions, and the forms of finding chemical elements in the tailings of processing do not prevent their inclusion in the biological cycles of living creatures, therefore, the radical measure to prevent progressive morbidity is only the extraction of metals from the tailings of ore processing during disposal. It is established that the speed and direction of exomorphodynamic processes are determined by the parameters of movement of the mobile fractions of metallic minerals. The activity of natural leaching processes is a consequence of the development technologies and can be reduced by using controlled leaching of metal-containing minerals. The formula for the dependence of the parameters of chemical pollution on the distance to the pollution focus is obtained. The assessment of social damage from the effect of the polluted environment on health of the population only by expanses on the treatment of the population and social security services during disability is incorrect, because the impact of metals is much larger. The use of tailings for processing waste from the mining cycle after bringing it to a safe state in terms of metal content allows to reduce morbidity of workers and the population of residential areas of mining production.
