The ecological problems arising in open-pit and underground production of solid-mineral deposits are described, the basic advantages of underground leaching, the reasons and sources of contamination of the environment during production of the deposits by underground leaching, and measures for protecting the air, soil, and surface and underground waters, and methods for rehabilitating underground waters are presented. Investigations of natural and artificial neutralization of waste underground-leaching solutions during the interaction of the solutions with technogenically unchanged rocks, performed at one of the uranium deposits, are described. An ecological monitoring scheme is proposed for the Khiagdin deposit. |
