The relevance of the work is caused by the need to survive the mining industry during the protracted post-reform crisis and to minimize its negative impact on the ecology of the region through the development of technogenic mineral resources. Purpose of work. Substantiation of the possibility of replacing the traditional components of the filling composite with own or attracted man-made wastes after their processing to a level that meets the conditions of environmental safety and economic feasibility. Research methods: systematization, analysis and generalization of theoretical and experimental research in this area, as well as patent data. Results. A generalization is made, the result of an analysis of the mechanism and rates of accumulation of waste from mining and processing of mineral raw materials is given, and a multifactorial mathematical model of degradation of environmental ecosystems as a result of the impact of waste is formulated. A historical background is given and an assessment of the development of mineral deposits with backfilling with hardening mixtures based on utilized man-made waste in a closed cycle is given. A promising method of activating the binding components of the hardening mixture is recommended, treatment in a high-speed mill - disintegrator. The results of experimental studies of the possibility of using metallurgical slags of the Chusovoy metallurgical plant as a binder and as an inert filler of ore dressing wastes of PJSC Uralkali are given. It is shown that if the content of unrecovered metals in industrial waste is more than the background level, they can be disposed of after the extraction of metals within the framework of a single technological cycle of waste-free production. It is concluded that when preparing a filling composite, it is possible to replace traditional commercial components with man-made waste from mining and processing and metallurgical industries after extracting useful components from them and neutralizing hazardous impurities. The prospect of the transition of mining production to an innovative principle of organization, which excludes the storage of waste, is noted, for which it is advisable to combine physical-technical and physical-chemical technologies at the design stage in the technological process of resource development. Conclusions. The involvement of man-made waste in a closed production cycle increases the environmental and economic efficiency of enterprises. Conversion of production to minimize waste volumes and their use in their own or in related production is an effective step towards sustainable development of the mining region.
