The relevance of the research is due to the need to stabilize the composition of the melting products of copper-nickel sulfide raw materials in the Vanyukov furnace. The goal of this research is to identify the most suitable methods for the aggregation of the real time data for the development of a mathematical model for control of the technological process of melting copper-nickel sulfide raw materials in the Vanyukov furnace. Statistical methods of analyzing the historical data of the real technological object and the correlation analysis of process parameters are described. Factors that exert the greatest influence on the main output parameter (copper content in matte) and ensure the physical-chemical transformations are revealed. An approach to the processing of the real time data for the development of a mathematical model for control of the melting process is proposed. The stages of processing the real time information are considered. The adopted methodology for the aggregation of data suitable for the development of a control model for the technological process of melting copper-nickel sulfide raw materials in the Vanyukov furnace allows us to interpret the obtained results for their further practical application.

The article covers the issues of increasing the efficiency of tunneling&cleaning combines “Ural”, widely applied at domestic potash mines. It is pointed out that it is possible to provide rational parameters of the process of destroying potash arrays with cutting tools of the executive bodies of mining combines. This assumption is based on the assessment of the drivers load which will reduce the specific energy consumption for ore extraction and will reduce the number of small unenriched classes in breakage products. The authors substantiate rational regime parameters of the operation of the planetary-disk executive bodies in the Ural combines. A method for automatic control of the tunnel&cleaning combine “Ural” is proposed, which ensures the implementation of the process of destruction of the potash massif with rational cutting parameters on the basis of information on the drivers load.

The Arctic region of Russia is of strategic importance to the country due to the presence of important sea routes, military bases and a wide variety of minerals. At the same time, despite the strategic importance of the region, its development is slow due to various environmental problems. In addition, there are various environmental problems that hinder the full development of the North of Russia (global warming, air, water and soil pollution). The threat of environmental instability is largely due to the activities of industrial enterprises in the region; as a result, the production process must be modernized in such a way as to eliminate or minimize possible risks to the environment. The article identifies the main problems of development of the mining and industrial complex of the Arctic region of Russia. The directions and ways of solving the identified problems, ways of achieving environmentally responsible nature management and establishment of circular economy in the region are considered. The main results of the study are the presentation of the relationship between the identified environmental problems and ways to solve them, the analysis of the negative impact of a number of mining companies on the Arctic environment, and the calculation of the economic effect of the introduction of water treatment facilities at the company of PAO MMC Norilsk Nickel.
