The article presents data on the possibility of using a magnesium binder from the dolomite of the Vaush deposit, which allows the use of dolomite and tailings in fastening in mine workings. The use of a cement binder pollutes the mined ore, contributes to the complexity of the technology of its enrichment and the extraction of a valuable component (concentrate). Therefore, the use of dolomite as a magnesium binder opens up new opportunities for improving the quality of mining, processing and preventing contamination of the mined mineral under underground mining conditions. The binder is only 8-22% inferior in strength to mixtures with standard cement and is suitable for construction in mine workings.
