Survey of the world practice of implementing energy-efficient technologies in terms of mining enterprises

Abstract

Purpose is the analysis of world practice of applying the best available techniques to increase energy saving and energy efficiency of mining enterprises being the important factor of the economic development. Methods. The research methodology is based on the scientific approaches: historical-evolutionary, interdisciplinary, integration, process, and situational. Methods of retrospective, categorical, and system analysis as well as modeling have been applied. The analysis was performed on the basis of both initial information sources (original texts of legislative documents, strategies) and material of the international analytical organizations (International Energy Agency, World Bank) as well as the data of official statistical records. Findings. For the first time, different variants of the best available techniques in Japan, the USA, and the EU have been analyzed as well as the role of a state in applying institutional measures of energy efficiency support, including mining complex, and prospects of its use in the Russian Federation. It has been determined that energy efficiency is the effective and economically feasible tool in reaching sustainable development of the national economy. It has been demonstrated that energy saving and increased energy efficiency may reduce the needs in investment, raise industrial competitiveness and consumer welfare as well as improve environmental protection owing to the reduced greenhouse gas emissions and decreased air pollution. Energy efficiency growth has direct effect upon the industrial competitiveness; it can be achieved by means of innovations. Originality. Emphasis has been put on the key scientific and technical aspects and approaches stimulating increased energy efficiency in the developed countries under the effect of strong, coordinated, and consistent national policy in different sectors of economy. Practical implications. The carried-out analysis is useful in terms of the innovative and technological development of different industries of the Russian Federation in the context of its complicated cooperation with European countries and the USA, dependence on foreign technologies, and limited access to them.

A Study of Heat Exchange Processes within the Channels of Disk Pulse Devices

“…The intensification of the gas dynamics and heat exchange processes within the disk pulse devices resulting from their operating space optimization is of great importance, especially in terms of improving the already available or developing new energy-efficient heat machines [4,[7][8][9][10][11]. Studies dealing with the improvement of the energy efficiency of disk devices, which involve renewable and environmentally safe energy sources, represent one of the most important trends of the energy complex development [12,13]. Current research in the field of pulse device improvement is aimed at optimizing technological parameters at the expense of changes in the working chamber geometry [14][15][16].…”

Geodiversity and Mining Towards the Development of Geotourism: A Global Perspective

“…In recent years, the importance of mining and sustainable development has been recognized for the protection of the environment and the reduction of pollution in mineral extraction and processing sites [65], technological development for clean mining [66], energy savings, and energy efficiency in the sector [67], as well as mixed reality simulations for compression and operation of mines [68].…”

Assessing the clustering effect for extraction and processing of raw materials (using the example of the Kuzbass cluster "Complex processing of coal and industrial waste")

“…According to various estimates, 17.6 to 18.2% of these mineral reserves are concentrated in Russia (over 157 billion tons) (Tolmachev et al, 2020). According to OPEC, oil reserves (at current production volumes) will last for 30-40 years, natural gas for 75-80 years, and coal for 400-500 years (Goncharenko et al, 2019). Consequently, coal will remain a strategic resource for Russia for a long time if compared to oil and gas (Salnikova and Grineva, 2021).…”

“…Currently, a working group on the development of effective coal processing and gasification, including underground, is functioning in the Ministry of Energy of the Russian Federation. The main task in regions with the developed coal industry (raw material regions) is to obtain the maximum effect from these processes (Goncharenko et al, 2019).…”
