FIELD: mining.
SUBSTANCE: invention relates to mining and can be used in extraction of potassium ores using hardening backfill based on salt wastes. Invention contains composition of filling mixture. Filling mixture contains potassium ore processing wastes, metallurgical slag, basalt fibre and saturated salt solution. Potassium ore processing wastes used are halite wastes from potassium ore processing. Ratio of components is as follows, wt.%: halite wastes of potassium ore processing 48.5-55.6; blast-furnace metallurgical slag 14.0-21.0; basalt fibre 0.4-0.5; saturated salt solution – balance.
EFFECT: higher strength of backfill.
