By the method of mathematical planning of the experiment, the influence of the liquid-solid ratio and the content of waste of salt deposits in magnesia hardening backfill mixtures on their technological properties have been studied. The plan of the experiment has been chosen, the regression equations describing the influence of anhydrite wastes and halite wastes content on the density, spreadability and early setting time of backfillingsolutions, volumetric mass, and 28-day uniaxial compression strength of hardened materials have been obtained. As a result of the statistical analysis of mathematical models, the significance of their coefficients, adequacy, efficiency and the ability to calculate technological characteristics of backfilling mixtures by type and content of man-made raw materials have been estimated.
