FIELD: mining engineering.
SUBSTANCE: method for covering surface of tailings impoundments is to consistently cover the contaminated area with layers. As layers, inert materials are used in the following sequence: potentially fertile overburden rocks, sand and gravel mixtures, vermiculite, ash-and-slag wastes.
EFFECT: increasing the reliability of tailings impoundments surface covering, ensuring environmental safety of tailings wastes, reducing costs.
