Abstract
A schematic flow diagram of a method for the production of hardening mixtures using granulated slag, cement, anhydrite, crushed stone and tailings of metallurgical waste is presented. The largest specific weight of backfill types is shown, technical equipment of backfill components. The production of backfill mixtures at the Komsomolsky mine is described. It is found that the use of plasticized additives for backfill mixtures allows improving performance, increasing the operating efficiency of a backfilling system and decreasing the operating costs.
