Annotation: The article presents the optimal compositions and properties of backfill mixtures using waste rock sand, marble processing waste and copper smelting slag. It has been established that, in terms of their physical and mechanical characteristics, stowing mixtures based on waste are not inferior to mixtures based on natural materials. An analysis of previous studies has shown that very important positive results have been achieved in the field of improving energy efficiency and creating resource-saving technologies in the production of backfill mixtures to fill the mined-out spaces formed during ore mining. However, taking into account the tasks set for the mining industry of the Republic of doubling the extraction of minerals and the related analysis of the scientific results obtained on the development of energy and resource-saving technologies involving the use of industrial waste shows that in studies aimed at developing compositions of effective mixtures, in particular on obtaining backfill mixtures based on secondary products and chemical additives, there are insufficiently studied scientific problems, which indicates the need for a deeper study of these issues.
Keywords: backfill mixture, optimal compositions, copper smelting slags, marble processing waste, additive, waste rock sand.
