Improvement of the system of state management of subsoil use
- Authors:
- Vladimir S. Litvinenko
- V. E. Varshavskii
Russia, as one of the world's largest producers of minerals, is the world's leading exporter, and its mining industry plays a critical role in the economic and social structure of Russian society. The continuing decline in the production of mineral resources, the deterioration of the raw material base of existing enterprises, the enormous reduction of mining capacities, and the lack of measures to replenish them do not contribute to a favorable investment climate, which may lead in the very near future to a situation where a country with huge reserves of raw materials will practically lose control over their effective use. The main goal of the work is to emphasize the need for an urgent change in the system of state approach to the management of mineral resources by adopting the Russian Government’s Mineral Resources Policy. The concept of sustainable development of our economy requires an urgent revision of the former attitude to the consideration of issues related to minerals in the context of the unity of economic and social goals and objectives.

Hydrological and environmental expert assessment in the system of natural resource management
In light of current and forthcoming changes in the water use management system, there is an objective need for qualitative assessment of water bodies based on rent principles. In this connection, the role of hydro-environmental expertise as a way to identify and justify the main rent-forming factors determining the value of water bodies is increasing. Thus, the hydrological-environmental expertise becomes a specific tool for water use management.

Development of a business planning system for the development of mineral resources in the Republic of Karelia
- Authors:
- E. E. Kurgi
The methodology of UNIDO evaluation of investment projects has been improved. A new indicator of economic efficiency is proposed, which allows not only to uniformly assess the efficiency of investments and financial and economic activities of mining enterprises of the Republic of Karelia, but also to quantitatively assess the investment attractiveness of Karelian mineral resources development. The new indicator allowed to develop methodological recommendations (on the assessment of the value of the deposits, on the preparation of investment proposals, on the assessment of the investment attractiveness of deposits, on the development and examination of business plans of investment projects, on the assessment of financial and economic activities of enterprises), which could become the basis of business planning system of development of mineral resources of Karelia. The structure of the web-portal "The mining and industrial complex of the Republic of Karelia" was designed and the layout was created. An intensive full-time training course on practical business-planning has been developed and tested, which is intended for the specialists and entrepreneurs of the republic's mining and industrial complex.

Studies of geothermal energy in areas of modern volcanism
- Authors:
- A. V. Kiryukhin
Geothermal energy is the driving force behind geothermal processes: volcanic, hydrothermal and seismic, and manifests itself in areas of modern volcanism in the form of active volcanoes, hydrothermal systems and earthquakes. Hydrothermal systems represent the "useful part" of geothermal energy, which can be used within geothermal fields to produce electrical and thermal energy, as illustrated by the examples of the Mutnovsky and Pauzhetsky geothermal fields. Active volcanoes have not found any application in the energy sector. However, the energy contained in them can be released in the form of hydrothermal explosions, as discussed in the example of the cone of Avacha volcano. Earthquakes are the most dangerous mode of geothermal energy release. The study of anomalous phenomena of hydrodynamic nature in active hydrothermal systems and on active volcanoes continues.

- Authors:
- S. V. Slastunov
The technology of coal bed degassing using the effect of hydraulic impact and redistribution of rock pressure in the bottom-hole zone has been developed and tested in the mines. The basic technology provides hydraulic treatment of coal seam with water injection at pressure of 100-150 atm. Under the proposed technology, at the stage of flowing water from the well in the calculated mode, hydraulic shocks are realized by cyclic overlapping of the water flow, which causes pressure pulses with an amplitude of 170-200 atm. In addition, the technological variant of changing the rock pressure in the vicinity of the borehole by forming slots located along the helical line has been developed. Tangential stresses arise in the coal massif, which leads to increase of its permeability. The given technological variants provide increase of coalbed methane flow rate by 1.5-2 times.

Physical and chemical basis for the creation of sorption technologies for the management of highly saline liquid radioactive waste (mathematical modeling)
- Authors:
- V. A. Avramenko
By the example of sorption-reagent materials (SRM) based on inorganic hydroxides the factors influencing the efficiency of the strontium sorption process are considered. It is shown that formation of a poorly soluble sediment in the porous system of the sorbent matrix is possible either in the form of microcrystals in the pore volume or in the form of thin X-ray amorphous layers on the pore surface, which in turn affects the selectivity of strontium extraction. The peculiarities of strontium sorption dynamics by SRM are considered. Mathematical model of strontium sorption dynamics in sorption-reagent systems is presented which allows not only to predict sorption behavior of material, form content of all system components at any moment of time and at any point of a column, but also to explain distinctive features of the process.

Analysis of the impact of green space structure on public health
The most common diseases: influenza, acute viral infections (ARI), acute bronchitis, and some bacterial infections: tuberculosis and pneumonia were chosen as criteria indicators of public health, because we could get a fairly large sample size for them, as well as determine the impact of green spaces on public health. The results do not show any clear trends. In some cases, the relationship between green space and respiratory disease in children is reversed. Factors such as social composition of the population and air pollution also seem to play a significant role. In further analysis, it is necessary to increase the sample size and the number of parameters investigated, especially with regard to plantations.
