Abstract
The basic principles of organization and carrying out of hydrogeochemical monitoring according to the set parameters of chemical compounds of mine water at Yakovlevsky mine are given. Monitoring allows to estimate the activity of overflow and secondary moistening of rich iron ores in the mine. At carrying out of monitoring the general occurrence of hydrogen sulfide (H2S) of various genesis is revealed. The correlation of H2S and chlor- ionic maintenance was obtained. Zones of active water overflow from low-carbon limestone at horizons -425 m and -370 m were outlined. The possibility of corrosion of concrete and metals under the influence of H2S is shown.
