Ecological impact of elimination career Shaimerden on the environment

Abstract

Contained a general hydrological and hydrogeological characteristics and the results of hydrogeological forecast of
the rate of sinking career Shaimerden lead-zinc deposit in Shaimerden Kostanai region and technical solutions for the
first phase of land reclamation. Based on the analysis of the chemical composition of the natural lakes in the research
area of the field and observing the change in salinity of the lake water drainage receiver lake Koyandykopa carried out
is assess changes in salinity of its waters after the cessation of pumping, showing an increase in mineralization with
increasing evaporation from the surface. Forecast assessment of mineralization and chemical composition of the newly
formed lake on the site of a career built on the basis of its share in the groundwater inflow of water of different aquifers
and their chemical composition. The water quality limits its use only as conservation nature. The results of evaluation
of the environmental impact of remediation, providing temporary negative (dust) and positive (recovery of the aesthetic
appearance of damaged land) effects.
