FIELD: mining.
SUBSTANCE: erection of alluvial dam includes filling and bench by bench build-up of the separating dam 4, placement of hoses made of nonwoven geotextile filtering material 6 perpendicularly to the edge of flow propagation, filling of sleeves 6 with tailings 5 with formation of ground dam 4 in casing on the side of the tailing dump pond 8, and creation of impermeable screen of non-filtering geotextile material 7 to prevent filtration from the tailing dump on the side of the dam 1.
EFFECT: improved concentrating plants tailings deposition technology on dump bed soils of different water permeability, improved dam stability.
