Results of the study for the preparation of compositions of stowing mixtures of ASC (anhydrite-slag-cement) with maximal reducing the proportion of furnace slag and cement suitable for stowing of a worked-out space of mines are presented. Optimal compositions of the stowing mixtures on the basis of the modified anhydrite binder with Portland cement in the amount of 2.5–5% and potassium sulfate in the amount of 0.5–2% of raw material mass grinded until the specific surface of 4500 sm2/g have been determined; they meet all the requirements for stowing mixtures concerning their technological and physical-mechanical properties. The study results obtained show the possibility and perspectivity of using the modified synthetic potassium sulfate in compositions of stowing mixtures
