On the territory of the Russian Federation, exactly as in the rest of the world, huge amounts of mining waste have been accumulated. Most of them in open-pit mining are dumps of rock mass that occupy huge territories and have a significant negative impact on the earth's ecology. Most of the dumps are non-toxic and can be used for economic purposes where sand and stone are needed-in construction. However, the volumes are too large and only a small part can be used for the production of building materials. Another thing is if you need a large amount of rock for the construction of a long roadbed. There are other requirements for raw materials and the possibility of releasing large areas occupied by dumps. This direction has significant potential, because on the one hand, cheap construction raw materials, and on the other – a reduction in fees for the use of land (especially relevant for large mining and processing plants). The development of dumps as man-made deposits has its own risks and associated problems. However, it leads to the development of new technological solutions, which in turn opens up certain prospects for subsoil users. Currently, this direction is in its infancy, but the scale of the problem of storing dumps is already obvious. Therefore, despite the doubts, recycling of dumps is inevitable. It is also clear that this processing should be in huge volumes. And such volumes of use in the Russian Federation can only be achieved when building roads.

The most urgent task in the construction industry today is energy saving at all stages: from the production of building materials, products and structures to the construction of buildings and their operation. Combining these problems forms one of the directions of innovation policy of the majority of subjects of the Russian Federation – strengthening of local capacity and demonstration of solutions to improve energy and resource saving in construction. Building materials industry-one of the leading sectors of the economy, which is quite effectively uses secondary products of many industries for the production of various building materials. Development of production of building materials in this direction is associated with many aspects: the depletion of natural resources, high energy intensity of a number of technological processes of extraction and processing of raw materials; threat to environmental safety of the Russian Federation; lack of waste disposal sites; negative impact on the air, water and plant environment, human and animal health.

At present, in the Russian Federation there are no legislatively approved recommendations on the procedure, structure and requirements for the design of an emergency response plan for coal open-pit mines. Therefore, the development of this document at the mining enterprises is carried out independently, coordinating it with emergency response services serving the hazardous production facility. The absence of regulatory documents forces the enterprise management to make decisions on the structure of the document, forms and its content. This can lead to errors in conducting mine rescue operations when attracting additional forces and means from other units of rescue units. The relevance of creating a single document for everyone to draw up a plan for the elimination of accidents at sections has been repeatedly noted at production meetings with the participation of scientists, specialists from surveillance services and representatives of rescue units. In order to increase the emergency preparedness of enterprises, on the basis of studies of the current regulatory documentation of Rostechnadzor, the EMERCOM of the Russian Federation, Mines Rescue Service and scientific literature, an algorithm was developed for compiling submarines for coal open-pit mines. The analysis of accidents at the coal open-pit mines of the country made it possible to create a list of types of accidents encountered. Based on this, instructions have been developed for the actions of all workers in the mine for the initial period in the event of an accident. Taking into account the existing standard forms for coal mines, the developed document forms for open pits were developed, this will make it possible to unify emergency rescue operations regarding the preparation of documents. Scientifically sound solutions can be used to develop a plan for the elimination of accidents in the future at all mining enterprises engaged in open mining. The results of the work expand knowledge in the field of safety of coal open pit mining.

The Murmansk region is a region with the largest enterprises of the mining complex of the Russian Federation: KF JSC “Apatit”, JSC “Kola MMC”, JSC “Olkon”, JSC” Kovdorsky GOK”, JSC” North-West Phosphorus Company”, LLC”Lovozersky GOK”. They provide the majority of the country’s demand for phosphate ores, zirconium raw materials (baddeleyite), niobium, tantalum, and rare earth metals. In addition, the mining and processing of copper-nickel, iron and chrome ores, nepheline and ceramic raw materials, facing stone and building materials is carried out. At the same time, the activities of enterprises have a very negative impact on the environment. The issues of environmental safety in the extraction and processing of minerals, storage of mining waste in the Arctic zone of the Russian Federation are of particular relevance. The definition of sustainable development in relation to the mining industry is given. The concepts of available best technologies, circular economy, and “green growth” are considered from the point of view of their contribution to sustainable development. It is shown that the sustainable development of enterprises at the present stage is impossible without improving the environmental friendliness of production. The article analyzes the legislation of the Russian Federation and the practice of its application to identify mechanisms that promote sustainable development and eliminate barriers to the implementation of this concept in the mining industry. New technological solutions have been developed for mining enterprises of the Murmansk region, aimed at reducing aero-technogenic emissions, cleaning waste (mine) water, processing tailings of enrichment as man-made deposits, which allows both to minimize man-made environmental impacts and to increase the full use of mineral raw materials. Thus, the expediency of using the principles of “green growth” for the development of economic development policies in the Arctic is justified.

Development model based on the export of raw materials and high dependence on external economic conditions are among the main strategic threats to the national security of the Russian Federation in the field of economy. So, a number of states, not without reason, are trying to realize these threats in order to achieve their geopolitical goals by imposing different restrictions, various prohibitions and multiple sanctions. Some results of the analysis of the impact of the anti-Russian sanctions on the Russian foreign trade in 2014-2016 I present in this article. For the sphere of foreign trade, it is shown that the negative impact of prohibitions and sanctions, as well as adverse external and unfavourable internal processes and factors, had a greater impact, first of all, on the fuel and energy, petrochemical and machine-building complexes. The subjects of the Russian Federation with a high concentration of export and import, oil and gas extraction and metal-production were affected stronger than other regions. Along with this, the impact of sanctions and the response of the Russian government are stronger on the export of Russian products than on imports.

The article describes the current state of labour conditions and occupational morbidity, as well as measures to improve medical examinations of employees of mining companies. Hygienic studies have shown that labour conditions at these operations were and remain harmful. A general assessment of the workplace conditions of the main jobs at these companies corresponds to the 3rd and 4th Subclasses of Hazard Class 3. The levels of occupational morbidity and its structure are presented. More than 70% of newly detected occupational diseases in both underground and open-pit mining were registered among persons whose workplaces were classified as Subclasses 3.3-3.4. The article provides recommendations on conducting preliminary and periodical examinations of workers in accordance with the provisions of Order No. 988n/1420n of the Ministry of Labour and Social Protection and the Ministry of Health of the Russian Federation dated December 31, 2020, and Order No. 29n of the Ministry of Health of the Russian Federation dated January 28, 2021, that were introduced on April 1, 2021.

The article examines the national-state peacekeeping activities of the Russian Federation in the CIS, which is identified as a specific force peacekeeping, which in the interests of ensuring the national security of Russia allows the state to partially move away from a number of classical principles of peacekeeping and tasks of crisis settlement of the military contingents of the Commonwealth countries in conjunction with the warring parties. The modern peacekeeping model of the Russian Federation in the CIS is singled out and justified, which is implemented on the basis of a pragmatic and expedient approach in order to increase Russias strategic, political, military and other influence in the Commonwealth under conditions of sufficiently cool United similaroperations and the traditional hostile reaction of the leading countries of the West to Russian peacekeeping in the CIS. The specificity of the implementation of the named Russian model in the Commonwealth is explained by the rigid timeframes of taking urgent political decisions at the beginning of the peacekeeping operations of the Russian Federation, the scale and intensity of conflicts, their significant negative impact on the national security of the country, regional and international situation. The author formulates the concept of network peacekeeping with variable geometry, the use of which in modern Russian peacekeeping practice will increase the level of its national security.

Environmental security is currently one of the main components of the national security of the Russian Federation and includes not only control over the state of the environment, but also the implementation of measures to prevent the occurrence of environmental crises and disasters. The reduction of reserves of tradi-tional natural raw materials makes us look for new ways to replace it with different types of waste. The expe-rience of advanced foreign countries has shown the technical feasibility of this area and the use of more as a tool to protect the environment from pollution. However, almost all basic building materials can be made from waste or from waste in combination with natural raw materials. Due to the involvement of multi-tonnage waste in the production of ceramic materials of mass consumption, which include ceramic bricks, it is possi-ble to radically change the parameters of the raw material base of Russia, which also helps to reduce envi-ronmental tensions in the regions. Production of ceramic bricks  one of the most material-intensive sectors of the economy, so the rational use of fuel, raw materials and other material resources is a decisive factor in its successful development in the context of economic reform. In this regard, the use of waste in ceramic mate-rials is of particular relevance. On the basis of beidellite clay, waste: energy ─ ash and slag material and non-ferrous metallurgy ─ sludge Nickel-skeletal catalyst obtained ceramic brick with high physical and mechanical properties. Innova-tive proposals for the use of waste from the production of mineral wool in the production of wall materials – ceramic bricks based on fusible clay, the novelty of which is confirmed by a patent of the Russian Federation.

In the article, the authors pay attention to the issue of value preferences of Russian youth on the example of the one of the regions of the Russian Federation – the Kemerovo region - Kuzbass. The problem of political activity of young people is considered through the system of current legislation on youth, socialization and directly value orientations and preferences of young people. The main legal acts regulating youth policy in the Russian Federation are marked. As an empirical basis a number of methodological approaches were used-the system approach (D. Easton, G. Almond), the normative-value approach of J. Rawls, a method of expert interviews and questionnaire survey. The article shows the inconsistency of the value beliefs of modern youth, which is caused by the Russian model of democratic development.
