“… =V vein * α vein + V mr * α mr / V vein + V mr Similarly, the probability (P pr ) was calculated that, with the selective extraction option, the profit would be higher than with the gross mining, respectively. The profit for selective and gross options of mining was found by the formulae: (8) The cost of preparatory-development operations (PDO) for a system of sub-floor drifts in selective mining was defined as:…”

“…The thickness of such ores reaches 10-14 m, with an average gold content of 3 g / t. In connection with the growth of prices for precious metals, the cleaning-up of these mineralization has become profitable. For their work out, a system has been introduced for the development of sub-floor drifts with borehole breaks, which has made it possible to increase labor productivity at the stoped excavation and to reduce the prime cost of the extracted ore mass [8][9][10].…”

“…To provide the conditions for mine evolution at the final stage of development it is possible and desirable to perform the restructuring of georesources in the course of reforming, reorganizing and technical upgrading of production. In this case, it is possible to create new kinds of underground resources or convert the potential resources to actual ones due to the application of resource reproduction technologies [11,12].…”

The article presents the rationale of the concept and defines the principles of keeping the production potential of a mining engineering system at the final stage of development to prevent a mine closure accompanied by a range of social, economic and environmental problems resulting from the disturbance of habitat, as well as lithosphere and hydrosphere parameters, etc. This concept can be implemented due to radically new geotechnology solutions aimed at the alteration of gold ore mining and processing technologies with the eventual disposal of wastes to mined-out areas. At the current stage of mining science advancement, energy efficiency and resource saving are inseparably connected with the sustainable use and conservation of non-renewable natural energy sources and transition to the use of technology-related energy sources regenerated in the course of mining. In this case, energy efficiency is viewed as economically feasible electricity consumption achieved at the current level of mining machinery and technology development and mandatory compliance with environmental safety requirements. Enhancement of energy efficiency envisages the minimization of energy consumption for mining processes while maintaining the scale of production and tackling the accompanying non-production challenges. For the first time, for gold deposit conditions the author proposes general methodological approaches, in combination with a certain level of details, to the problem of systematization and estimation of opportunities of renewable energy sources use in the course of implementation of mining processes. The importance of the mentioned problem solution for mining sciences is in finding the evidence of the fact that in the course of implementation of mining processes within the framework of a mine various technology-related renewable energy sources are formed, which were not taken into account earlier, while the discovered objective laws of the formation of these energy sources, which, depending on the design and technology parameters of mining operations, provide a choice of preferable technological solutions to minimize the consumption of external energy supply by a mine. Development of new technical and technological solutions on the conversion of technology-related energy sources into electricity, its accumulation and consumption for in-mine needs will significantly minimize the consumption of external power supply, and in general it will enhance energy efficiency of mining operations and involve deposits located in remote and hard-to-reach areas in production.
