Abstract

Detailed study was given to the hydrogeology of the coal methane-promising Erunakovo region. We have established that all aquifers there are mutually related and form a single aquifer complex consisting of a series of microbeds of different water trahsmissivities and permeabilities. Two zones have been recognized in the Erunakovo region -of intense and slow water exchange (fresh- and brackish-water, respectively). Fresh waters with mineralization of up to 1 g/1 and pH = 7-8 occur at depths down to ∼300 m or, seldom, 500 m. Brackish waters have mineralization of 1-13 g/l and pH reaching 10.1. The higher mineralization is due to the higher contents of HCO3 - and Na and, sometimes, SO4 2, produced through sulfide oxidation, and Cl-, concentrated as a result of evaporation. In the study region, CO2 is not of mantle genesis but is the product of coal metamorphism.
