COMPOSITION OF FILL MIXTURE Russian patent published in 2012 - IPC E21F15/00 C04B28/08 

FIELD: mining.

SUBSTANCE: composition of a fill mixture comprising a ground acid domain pelletised slag, a superplasticiser SP-1, water and wastes of dressing of wet magnet separation of ferruginous quartzites, contained the following mixture as a binder - a mixture of jointly ground stale acid domain pelletised slag, current wastes of dressing of wet magnet separation and a superplasticiser SP-1, at the following ratio of components, wt %: specified slag - 49.8; specified wastes - 49.8; superplasticiser SP-1 - 0.4, and an inert filler - stale wastes of dressing of wet magnetic separation of ferruginous quartzites at the following ratio of components, wt %: binder -22.65; filler - 55.35; water - balance.

EFFECT: recycling of stale wastes of dressing and stale acid domain pelletised slag, reduced consumption of slag as a binding component, reduced water amount as mixture spread increases with preservation of required strength, increased recycling of dressing wastes to improve condition of environment in KMA region.
