| Summary: | Relevance and aim of the study. Improving the quality of metal ores in development of complex deposits by underground method is provided by the use of technology with the laying of the cavities hardening compounds, but the extension of the scope of technology development with the laying of the cavities hardening mixtures is limited by lack of binding cements. Reduction of deficit in binders as a means of improving the quality of extracted ores through the involvement of mineral waste in production is an urgent task of mining science and the aim of the research. Methods. Research methodology includes the analysis of efficiency of ore extraction through the use of anthropogenic resources in underground development of deposits of metal ores, activation of components of solid mixtures in a laboratory ball mill for differentiated parts of the backfill array and interpretation of the results. Results. The authors have proved the possibility of reducing the deficit in the goods by making the binder solid mixtures on the basis of the utilized slag. The paper introduces the results of studies of the activation parameters of the granulated blast furnace slag in ball mill. The authors determined the concrete mixture strength dependence on duration of slag activation and recommended the economicmathematical model to determine the amount of profit from the disposal of tailings the metallurgical mining industry, taking into account the lost in ore extraction. It is shown that the disposal of hazardous during storage of mineral waste allows solving a set of problems in mining industry. Conclusions. Improving the quality of ores in their extraction and extension of application area of resource-saving technologies of exploration with voids bookmark with hardening mixtures is achieved by using available and cheap tails of technological processes. |
