FIELD: mining.
SUBSTANCE: invention can be used at potassium enterprises for reclamation of salt dumps slopes. For this purpose, overlapping geotextile cloth impregnated with bitumen-polymer emulsion (liquid rubber) is laid on prepared slopes surface, after full drying of emulsion counter barriers directed from across slope with pitch of 5-10 m depending on their curvature are installed and fixed from above, then counter filtration screen is formed from polymer materials and backfilling of potentially fertile and fertile soil layers is carried out.
EFFECT: reduced labour intensity and cost of operations at reclamation of salt dumps slopes and higher efficiency.
