THE MAIN RESEARCH DIRECTIONS OF HYDROSPHERE OF KIZEL COAL BASIN
The Exploitation of Kizel coal basin located on the Western Urals, carried out more than 200 years. A characteristic feature of Kizel basin during its operation is the formation of large volumes of acid mine water containing a variety of contaminants in amounts many times higher than the MPC for water bodies drinking and commercial fishing importance. As a result of discharge of mine water pollution were subjected to strong not only almost all surface water bodies in the basin, but also such major rivers as the Perm region like Yaiva, Kosva, Usva, North and South Vilva. In some cases, mine water polluted groundwater clean. Coal production did not result in the termination of the negative effects of underground coal mining on the hydrosphere coal basin. Therefore, the investigation of surface and underground mine water and swimming pools were conducted during the period of its operation, and continue to be carried out after the complete cessation of coal mining.
