TAILING FOR STORAGE OF WASTE MINING ENTERPRISES

摘要

FIELD: mining engineering.;SUBSTANCE: tailing pile contains sections separated from each other. The bottom of the sections is shielded by a strong film of polymer material on which a layer of limestone 300-400 mm with grain dimension 3-10 mm is placed. On the layer of limestone, drainage pipes with a diameter of 200-300 mm, which is resistant to acidic attack. The tailing dump is filled with wet storage, and the storage of sands in a dry state.;EFFECT: invention makes it possible to improve the ecological safety of tailings storage by removing dissolved toxic substances from the sand column through the drainage wells into a layer of limestone located at the bottom of the tailing pond and in a settling pond.;5 cl, 3 dwg
