FIELD: mining industry, specifically, exploitation of tailing dumps of dressing mills. SUBSTANCE: sections outlined within limits of tailing dump with certified content of useful components are finished off by way of their washing with high-pressure water jet coming from nozzle of hydraulic giant installed in hole drilled from underground working. Formed hydraulic mixture is delivered by gravity through transport hole into underground working and is shipped to dressing mill to recover mineral resources. EFFECT: reduced expenditure for finishing off. 1 dwg
