The admissibility of replacing traditional cement, used as a binder with magnesium-containing man-made waste in the preparation of a construction and fill mixture is justified. The possibility of replacing the traditional specially mined aggregate in construction and fill mixtures is proved. The results of testing samples after cementing and a construction-fill mixture prepared on the basis of man-made waste are presented. The positive effect of mechanical activation of the backfill mixture components on its rheological properties and strength characteristics of the fill mass is studied. The use of lignosulfonate as an additive was confirmed to improve the binding and rheological properties of the backfill mixture. The involvement of man-made waste in the closed cycle of the main and auxiliary production reduces the volume of man-made massifs, which significantly reduces the impact of mining production on the environment.
