Geoecological Challenges of Mined-Put Open Pit Area Use in the Ural

Resumo

Mining and processing industry forms mining landscape. Reclamation of mined-out areas is an efficient way of the environment protection in mining regions. It is rational to make mining-disturbed lands suitable for further use by taking mineral mining and processing waste. Justification of technology of placing waste in the mined-out void of Vostochny open pit of Magnitogorsk Metallurgical Plant at Magnitnaya Mountain (Chelyabinsk Region) is based on the analysis of hydrodynamic and hydrochemical history of the project, laboratory studies into interaction of backfills with quarry water and prediction modeling of change of conditions in the course of backfilling the open pit by means of modeling hydrogeomigration.
