Within early warning and technological hazards, the need to notify, and to identify, assess and provide the necessary information about the sources of potential hazards is of particular importance. Since there may be causal links between natural and technological disasters, there are increasing concerns that the available knowledge base does not allow for timely warning or relief measures for many hazards. Any early warning system aims to reduce risk as a measure of potential environmental and economic damage. Such reduction, as a rule, is achieved by continuous study of information on the state of functioning of the natural-technical system. Hence the task of systematic collection, accumulation, processing and analysis of information arises. The system of continuous observation, control and analysis of the environmental situation for subsequent diagnosis and forecasting of the state of natural objects is realized within the framework of monitoring, which is performed at three levels - global (planetary), regional and local. The Sakha Republic (Yakutia) is the largest region of the Russian Federation with a highly concentrated natural-resource potential, providing full-scale projects of national economic development of interregional and federal signi cance. Yakutia, the area of which is 20 % of Russia’s territory, is a giant natural enclave in geotechnical terms, the administrative boundaries of which cross many geographically heterogeneous ecosystems of seven neighboring territories (administratively independent subjects of ownership). The article considers and reveals the main directions of the early warning system to prevent socio-natural risk as applied to Yakutia, taking into account its natural-territorial uniqueness.

The large amount of peaty soils on the territory of the Russian Federation, especially in the Arctic zone, necessitates the study of their temperature regime and thermophysical properties. The paper presents the results of an experimental study of the thermal conductivity and amount of unfrozen water in sandy soils with varying degrees of peat content. Experiments were carried out on samples with a damaged structure, which were represented by slightly decomposed peat, medium-grained river sand and their various mixtures. It has been established that the degree of peat content affects such physical values as porosity, thermal conductivity and the amount of unfrozen water. For thawed peaty sandy soils, as the degree of peat content increases, the porosity value increases. For both thawed and frozen peaty sand soils, thermal conductivity decreases with increasing degree of peat content. Moreover, the thermal conductivity for frozen soils are higher than for thawed soils. The amount of unfrozen water also depends on the degree of peat in the soil and decreases as it increases. The measured thermophysical properties of peaty sand soil can be used to model the temperature regime in the area of frozen and thawed peat soils.

For the effective enrichment of gold-containing concentrates and heavy concentrate with a high content of magnetic minerals, a beneficiation method in a jigging machine with a magnetic system has been proposed in the laboratory of the Laboratory mineral processing of the Institute of Mining of the North SB RAS. In the proposed method, a combination of gravitational enrichment and magnetic separation is carried out in a jigging machine. The most important factor in the process of effective extraction of gold from concentrate enrichment products containing iron scrap and minerals with high magnetic susceptibility in a jigging machine is the constant loosening of the forming natural bed. Subsequently, the method was improved and an electric pulse source was developed to create a pole-alternating magnetic field, which makes it possible to ensure a loosened state of the bed. A physical and mathematical model has been developed based on a Fokker - Planck type equation to determine the probability of particles passing through the thickness of a bed under the condition of the required state of loosening. Approbation of the model shows that the obtained calculations correlate with the results of experiments on a jigger with an electromagnetic installation under the conditions of the jiggering process: jigger cycle frequency 210 min-1, bed height 80 mm, amplitude 6 mm and pulse duration of the pole-alternating magnetic field from 0,1 sec. The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic No. 0297-2021-0022, Unified state information system for recording the results of research and development work No. 122011800089-2) using the equipment of the Center for Collective Use of the Federal research center ҺYakut Scientific Center of the Siberian Branch of the Russian Academy of Sciencesһ (grant No. 13.TSKP.21.0016).

The study is aimed at solving the urgent problem of stabilizing the temperature regime of construction sites and operation of engineering structures in the permafrost zone of the Republic of Sakha (Yakutia) and a changing climate. The currently used method of soil cooling using seasonally operating cooling devices, despite its effectiveness, requires a long exposure time and significantly delays construction time, which in some cases is unacceptable. In order to evaluate the effectiveness and prospects of the technology of rapid soil freezing using solid carbon dioxide (dry ice) for cooling permafrost soils, a full-scale experiment was carried out. To conduct the experiment, a test site was equipped at one of the construction sites in Yakutsk with the installation of cooling and thermometric wells. During the experiment, the temperature field of the soil and the temperature inside the cooling well were recorded. As a result of the experiments, actual data were obtained on the distribution of temperature in the soil depending on the temperature and distance from the cooling well during the cooling effect and after it. The results obtained provide grounds for assessing the tested technology as promising in the conditions of permafrost soils in Yakutia.

This work is carried out in the laboratory of the Laboratory of mineral processing Institute of Mining of the North and is a continuation of research conducted on a steep-slope concentrator protected by a patent of the Russian Federation. Earlier, on the basis of experimental work carried out on a steeply inclined concentrator, unsatisfactory extraction of the useful component, clogging of the concentrate in the storage chambers, uneven dynamic processes over the entire area of the working surface of the concentrator were revealed. In order to further improve the concentrator, a shut-off valve was installed at the nozzle for water supply throughout the entire volume of the concentrator. Experimental studies have been carried out to improve the efficiency of mineral separation, where special attention is paid to the stability of the dynamic processes occurring throughout the working chamber of the concentrator, the exclusion of the formation of stagnant zones due to flow control and improving the quality of the concentrate as a whole. Thanks to the adjustment of the operating modes of the concentrator by the shut-off valve, it is generally possible to get rid of these negative phenomena and significantly increase the area of the effective working area. The most rational results are determined when the deck of the concentrator 700 is tilted, where the extraction of heavy fraction (magnetite) reaches 91.16 % at a speed of 0.35 l/s. The use of a shut-off valve makes it possible to regulate the flow of water inside the concentrator, at which conditions for effective separation of mineral particles are found. The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic No. 0297-2021-0022 of the unified state information system for recording research, development and technological work for civil purposes No. 122011800089-2) using the equipment of the Center for Collective Use of the Federal research center "Yakut Scientific Center of the Siberian Branch of the Russian Academy of Sciences", grant No. 13.

The article presents the results of many years of research in the field of air (dry) method of separation (enrichment) of minerals. The results of a manufactured pneumatic separator of the POS-2000 type, which passed pilot tests in a number of gold ore deposits in Yakutia and the Amur region, are presented. The work presents developments to improve the design and production parameters of the installation, where reduction of weight and size parameters is relevant and in demand at this time, especially for mobile mobile versions of enrichment plants. The article shows laboratory experimental work aimed at a detailed study of the dynamics of the behavior of multiphase media in complex chambers, both in simplified laminar and turbulent cases. For a more detailed study of the influence of different air flow on the process of separating various minerals by density and size, an experimental laboratory installation with three toroidal zones was assembled, consisting of a flexible transparent plastic reinforced pipe, bent in the form of a screw (screw helicoid). The maximum angles of rise of particles along the internal boundary of the laboratory stand, the speed of soaring of particles depending on density and size, the maximum angles of hovering and soaring at different air speeds are considered. Studies have been carried out on the distribution of particles in the radial section in different sections of the pipe (S1-S3), in which angular differences in distribution were obtained due to different levels of the ratio of centrifugal and gravitational forces, at tested speeds and turning radii. Further research aimed at the possibility of modifying the existing pneumatic separator to reduce weight and size and the development of a new type of centrifugal pneumatic separator are shown. The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic No. 0297-2021-0022 of the unified state information system for recording research, development and technological work for civil purposes No. 122011800089-2) using the equipment of the Center for Collective Use of the Federal research center "Yakut Scientific Center of the Siberian Branch of the Russian Academy of Sciences", grant No. 13.
