FIELD: mining.
SUBSTANCE: invention relates to mining industry and may be used in development of mineral fields with filling of the mined space. The composition of the filling mass includes portland cement, a filler and water, besides, it additionally comprises a surfactant of a superplasticiser SP-1, and the filler is represented by stale wastes of dressing of wet magnetic separation of ferruginous quartzites and converter sludge at the following ratio of components, wt %: portland cement - 8.0; specified sludge - 12.70; specified wastes - 56.64; superplasticiser SP-1 - 0.08; water - balance.
EFFECT: exclusion of natural fillers, increased mobility of filling mass and increased volumes of recycled anthropogenic wastes for considerable improvement of environment in the region.
