The processes of controlling the ore-containing mass are refined and detailed, and the mechanism of interaction of stresses and deformations during underground mining of ore deposits is detailed. The properties of the massif and the role of faults and macrofractures in the development of deposits of complex structure are systematized. A methodology for studying stresses and deformations of rocks is given. Regularities of array maintenance at the interface site are established. Quantitative values of changes in physical and mechanical properties and stability of rocks in the interface zone are given. The array is differentiated by the magnitude of the acting stresses in various phases of the connection. The calculation of stresses for specific conditions with the determination of the reliability of the mining site was performed. Patterns of stress and strain changes over time are noted. An explanation of the phenomenon is given from the standpoint of the interaction of structural rock blocks in a discrete field of the array.
The article substantiates the need to strengthen the mineral resource base for the production of non-ferrous metals through the involvement in the operation of substandard raw materials, primarily those stored in tailings dumps for the enrichment of metal ores. The results of the analysis of reserves of ore deposits are presented in comparison with the situation in the world. Quantitative data on the state of the mineral resource base of non-ferrous metal ores in Russia and the provision of industry with metal raw materials are given. The role of mineral resources in protecting the geopolitical interests of Russia is shown. It is noted that Russia lags behind technologically developed countries in a number of indicators of production and consumption of mineral resources. It is concluded that the development of technogenic deposits using innovative technologies is a real step towards strengthening the mineral resource base of Russia, therefore, research on the direction of mining mentioned in the article is relevant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
