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.

Deep sea solid mineral resources (SMR) of the World Ocean, such as ferromanganese nodules (FMN), cobalt-manganese crusts (CMC) and the depth polymetallic sulphides (DPS) should become an alternative source of mineral resources in the near future. Reliable and productive complexes are necessary for the implementation of deep-sea mining on an industrial scale, which will be able to develop deposit with a minimum ecosystem load. So, the main problems in technological solutions are the collection or separation of SMR at the bottom and lifting them to the surface. As a technical solution, it is proposed to use a special construction draghead device for FMN and CMC collecting and separating from the bottom. The distinctive feature of the device is a vertical axis of rotation of the drive engine and the working body, which can be represented by a faceplate or a crown, the working element with the engine are concentrically inscribed in the casing with the catcher, which enclose the loosening zone, protecting surrounding water area from the turbulent mud and separated fractions. Nodules and crusts lifting using the draghead is carried out in the form of slurry through a pipeline.

For the last thirty years, UNESCO has been repeatedly raising questions of accessibility and quality of education for every child, teen, and adult by implementing the “Education for All” program. The new concept of education proposed by UNESCO aims at transforming people’s lives and formulates the following sustainable development goal “To provide inclusive and equitable quality education and create lifelong learning opportunities for all. One strategy for achieving this goal is to use and develop information and communication technology (ICT) to strengthen education systems, knowledge dissemination, access to information, and quality and effective learning. The aim of the work is to increase the efficiency of students’ learning of geometrical and graphic disciplines by developing a pilot electronic course in LMS Moodle and special software implementing elements of individualization of the learning process
