Activation of ore process waste for preparation of consolidating mixtures

The article discusses the challenge of providing mining operations with raw materials for preparation of consolidating stowing in mining ore deposits using the underground method, the relevance of which increases with the complexity of the conditions for mining raw materials and the scientific and technical progress. The result of reviewing the theory and practice of managing the stressed state of the rock mass with preservation of the environmental ecosystems is presented. The results of multifactorial studies of using the DESI-11 activator-disintegrator are given. The expediency to use the physical and chemical processes of mechanochemical activation of the metal-containing raw materials is justified which allows using tailings of primary ore processing as binding components. The possibility has been proved of extracting metals and obtaining consolidating stowing of sufficient normative strength based on binders and fillers made of ore processing tailings. It is shown that after their activation in the disintegrator, process tailings can be used without restrictions, including those of the sanitary requirements, which creates a significant ecological and ecological effect. Activation of the process tailings opens up the prospects to use environmentally friendly mining systems with backfilling of the mined-out space with consolidating stowing by creating a practically unlimited source of binders and inert components for consolidating stowing. The parameters of mechanochemical activation of the ore process tailings have been optimized.
