Results of the study of using the synthetic calcium sulfate anhydrite, produced at the interaction of concentrated H2SO4 and flour limestone, for preparation of formulation of filling mixtures of a anhydrate-slag-cement type with maximum reducing the part of blast-furnace slag and cement suitable for stowing of the mined-out space of mines are presented. Optimal compositions of filling mixtures on the basis of the modified anhydrite binder with 2,5–5% of Portland cement and 0,5–2% of potassium sulphate from the mass of raw material grinded up to the specific surface of 4500 cm2/g have been determined; they meet all the requirements for filling mixtures concerning technological and physical-mechanical properties.
