Abstract

Mining and Mineral Engineering has a powerful impact on the environment. In the areas of mining taking place radical changes of geological environment that are irreversible. Groundwater, as part of the four component hydrogeological system undergo significant changes. The investigation hidrogeochemistry processes in the groundwater aquifer of quaternary sediments in the North mining plant. Investigated aquifer studied quaternary sediments, water containing loess loam, Valley Saksagan - alluvial sands. The aquifer distributed throughout the territory of studies. The most powerful man-made elements that have an impact on groundwater is storage of waste rock, industrial site, quarries and dumps. Research based on the results of hydrogeological monitoring carried out geological and hydrogeological Krivorozhskiy party since 1978. For selected research results of the monitoring of 24 wells. Analysis of observations of the chemical composition of groundwater in the North mining and processing plant and existing man-made objects showed that hydrogeochemical situation came into equilibrium-nonequilibrium nature. The purpose of the study is to assess and forecast of man-made mineral zone supergene iron ore deposits. Analysis of possible processes hydrolysis of silicates and aluminosilicates water aquifer of quaternary sediments. Found processes of transition to montmorillonite and kaolinite. Made construction of two-dimensional diagrams of the system HCl-H2O-Na2O-MgO-SiO2 at t = 25 0C and lg [H4SiO4] =-3,99 rezultatmy chemical analysis of water samples from wells. Built map-scheme of hydrolysis of silicates and aluminosilicates in the territory as of March 2016. Analysis of spatiotemporal distribution supergene processes showed their transient nature and strengthen over time. Calculations shown activation of supergene processes in water aquifer of quaternary sediments in the territory North mining and processing plant to establish equilibrium with kaolinite, resulting in increased salinity of groundwater, magnesium ion content and hardness.
