In this paper, we consider the need to create an algorithmized digital platform for the development of electric charging networks of road transport and to optimize the load on the current power grid complex. In modern conditions, this platform can become an example of a mechanism for public-private partnerships and the development of environmentally friendly transport. The purpose of the platform is to provide users with up-to-date information about the state of the electric vehicle battery, reduce the cost of creating a network charging infrastructure for electric vehicle transport, automated resource accounting for power supply companies, and other services. The use of information technologies to combine the processes of economic relations in the field of energy sales services will attract funds for infrastructure development by increasing the load factor of generating capacities and unloading power centers. In the article, the authors propose a digital platform architecture using modern technologies such as IIoT, Vehicle to Grid (V2G), Machine learning, Big Data.

Mining enterprises are widely introducing digital technologies and automation is one of such tools. Granularity monitoring, namely, the size determination of rock mass pieces is a common operational component of the processes that extract minerals by open-pit mining. The article proposes an approach that, in addition to the lump size distribution, makes it possible to estimate the lump form distribution as well. To investigate the effectiveness of monitoring the form of blasted rock mass lumps, the authors conducted experiments in four stages related to the rock condition. They include geological occurrence, explosive crushing, trommelling, and mill crushing. The relationship between these stages is presented and the change in the lumps fragment form is traced. The present article proposes an informational and analytical model of the processes at mining enterprises, extracting minerals by open-pit mining, as well as an algorithm for determining the lumps form and obtaining their distribution in the rock mass.

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.
