Geochemistry of ore-forming hydrothermal fluids of the world ocean

The most complete results of the study of hydrothermal ore-forming solutions geochemistry in the Russian and international expeditions to deep-sea hydrothermal fields of the world ocean are analyzed. Solutions of both high and low salinity with respect to seawater are formed in the discharge zone of fluids. Positive correlation of ore components with the chloride ion and negative one with the pH value may indicate the migration of components in acidic hydrothermal solutions in the form of chloride complexes. Hydrogen sulfide is associated with the significant positive correlation with metals, which indicates reducing conditions forming in ore-bearing hydrothermal solutions. This is confirmed by the close relationship of ore components with hydrogen. The transfer of metals mainly in the form of chloride complexes at high temperatures of the solution is confirmed by the results of our thermodynamic modeling. Methane is characterized by negative dependence on temperature and concentration of ore components, associated with positive dependence on pH and negative one on hydrogen sulfide. Each of the observed dependencies can testify against abiotic theory of income of methane in hydrothermal solutions. The following geochemical indicators are the most promising for the discovery of new ore deposits and the organization of geochemical monitoring during the development of already discovered fields: Eh, pH, Cl, Fe, Mn, H 2 S, CO 2 , H 2 and possibly CH 4 .

Application of the geoelectrochemical method for prospecting of oil and gas deposits in the Barents and Kara seas

The use of the geoelectrochemical method of ion-selective electrodes for continuous recording of hydrocarbon micro-components – heavy metals – during the vessel movement to search for oil and gas deposits on the shelf is justified theoretically and experimentally. The existence of «jet» halos in the water column above the shelf oil and gas deposits is discovered experimentally and the method of geoelectrochemical ion-selective electrodes as well as the developed instrumentation for recording these halos is described. The application of a new geoelectrochemical method for prospecting in motion (without sampling) both structural and non-structural oil and gas deposits on the shelf is justified.

The concept of reducing the risks of potash mines flooding caused by groundwater inrush into excavations

Results of the analysis of factors influencing the probability of accidental groundwater inrush into mine workings of salt (potash, potassium and magnesium) mines are given in the article. The cases of the potash mine flooding that occurred in different countries with developed mining industry are given. It is shown that at the present technical and scientific level of solving this problem the unexpected groundwater inrush in potash mines usually results in the shutdown of the enterprise and negative ecological consequences. It is pointed out that the underground waters flow into the mines through water-conducting fractures of either natural or technogenic origin which location and influence on a mine was almost impossible to predict at the design stage under existing regulations. The concept of reducing the risks of potash mine flooding caused by underground waters in-rush is formulated. Administrative and technical measures which allow reducing the risks of potash mine flooding caused by groundwater inrush into the excavations are considered.

On the design features of underground multiple gassy coal seam mining

The analysis of the industry regulatory requirements and the world design experience of underground multiple coal seam mining is provided. The main problems of intensive longwall mining of multiple flat gassy coal seams as well as methods for determination of high rock pressure zone parameters and seams interaction are considered. The examples of a number of mines in the Kuzbass and Pechora coal basins show that the design of multiple seam mining and the choice of longwall panel parameters were often made without taking into consideration influence of surrounded seams that leads to essential complication of conditions for mining operations and decreases the technical and economic indicators of mining. The existing industry regulations do not allow considering complex influence of factors in multiple coal seams mining fully. On the basis of field, laboratory, and numeric research results it is noted that recommendations for pillar positioning in contiguous seams ensuring efficiency and safety of multiple seam longwall mining can significantly differ in case of liability of coal seams to spontaneous combustion, high natural gas content, influence of multiple seam mining onto daily surface, and difficult conditions of entries maintenance. The importance of having information on the stress-strain condition of the rock mass at a design stage and its changes in the process of multiple seam mining is shown. The need for industry regulations updating for the purpose of a more detailed definition of a form, size and a location of high rock pressure zones as well as stress parameters in these zones is noted. A set of recommendations for effective and safe multiple seam mining is developed.

On the necessity of taking into consideration the increment of the growing stock in cadastral valuation of lands of forest fund

Currently there are no methods of cadastral valuation of forest land although the area covers 2/3 of the territory of the Russian Federation. In 2002, the Federal Land Inventory Service of Russia proposed a method but it failed to find practical use due to the complicated calculation of the cadastral value according to the Faustmann formula and lack of open access to some information about the forest fund and was totally abolished seven years later. There were several reasons for abolishing the method and the main reason was lack of methods to predict a supply of wood to the age of maturity when the cadastral assessment was carried out in the plantations under the age of main felling. The author proposes to take into account the current growth rate of the growing stock per year on one hectare of land in the cadastral evaluation of forest fund lands. Based on the increment of the growing stock it is possible to construct a mathematical model of changes in the forest reserve to the age of maturity. The author suggests using the existing forest inventory materials to build the model. By updating existing data you can obtain any inventory indices including the growing stock in different age plantations. The resulting inventory of plantations at the age of maturity is recommended for cadastral valuation of the forest fund lands. The calculation of the cadastral value of forest land for one taxation quarter with and without current increment of the growing stock is given and the difference is 37 %.

Stability of productive well operation in a steam hydrothermal field

A condition of well operation stability based on agreement of indicator characteristics of well and aquifer throughput capacity is considered. Two hypotheses of the stability state are examined: with one and two possible combinations of characteristics. It is shown that taking into account resistance between the wellhead and the environment with constant pressure helps explain all the features of wellhead pressure and flow-rate relationship of steam-water wells based on the hypothesis with one combination (when the operating point is located on the ascending branch of a well characteristic). The throttling effect on the wellhead which was used in the development of the Mutnovka steam hydrothermal field in order to stabilize the well operation is explained.

Scientific heritage of academician Nikolay Semenovich Kurnakov

Once N.V.Lipin, a professor of mathematics at the Leningrad Mining Institute, told N.S.Kurnakov that M.V.Lomonosov had complained about his lack of familiarity with mathematics. The outstanding scientist replied «That’s absolutely true, and I have already told you about it: we all need mathematics, and the more chemistry develops, the more it needs a mathematical justification». According to one scenario of the international nongovernmental organization, the Club of Rome, there will be a three-fold decrease in the world’s raw materials resources and multifold volume reduction in industrial production by the middle of the 21st century. Another scenario claims that raw materials will reduce only by one third, and the volume of industrial production will remain at the level of the beginning of the century. Not only the first scenario, but also the second one forecasts industrial stagnation. It is unacceptable for dynamic and sustainable development of the technological civilization. Intensively developing economies in China, India, Brazil and Russia defy the forecast of the Club of Rome, as it has not taken into account the possibility of scientific and technological progress in reducing energy consumption and using alternative sources, as well as the increased technological potential of the humanity. Due to depletion of the main sources of energy (oil and gas), many experts link the future of the world’s power industry with the possible use of solid energy resources. From the environmental point of view solid fuel gasification technology is the most preferable. As the calorific value of producer gas is relatively low in comparison with natural gas, some research of possible use of producer gas (as an alternative to natural gas which is available not in all regions) at Russian industrial enterprises has been conducted.

Complex processing of apatite-nepheline ores based on the creation of closed-loop process flow sheets

The article presents the chemical and engineering fundamentals of processing apatite and nepheline concentrates directly on the Kola Peninsula. Implementation of the existing separate processing of nepheline and apatite concentrates demonstrates inefficiency of these technologies due to the formation of waste calcium sulfate and calcium silicate, which have so far not found a practical use and are wastes stored in sludge repositories of the Russian Federation. Suggested new scientific and technical solutions will allow enterprises to significantly increase the volume of production of new in-demand marketable products due to rational and complex use of mineral raw materials of the Kola Peninsula, reduce their costs while decreasing the volume of rock extraction and eliminate waste creating a closed-loop technological cycle of processing apatite and nepheline ores.

Nanobar code as multi-purpose two-dimensional notation with new features

The article gives an analysis of the current standard two-dimensional codes, showing their features and applications. It was concluded that the feasibility of developing a new type of two-dimensional codes, the Nanobar code (NBC), in which information can be open (available) and, if necessary, closed (unavailable) to the user through the use of cryptographic encryption techniques. At the same time the new codes provide a significant increase in the volume of coded information that allows us to recommend using them as a local database, in particular for the issue of electronic technological certificates and product passports, personal dog tags for the military, athletes and others. It is noted as an important characteristic that the Nanobar code is able to encode different types of digital information. Due to its characteristics, the NBC is proposed to use as an identification number and protect legal products against counterfeiting. Two variants of the NBC technology application are proposed – with laser printing and printer. For reading information from the NBC, special software was developed, including mobile applications that allow using a smartphone to read the NBC. The basic scope of the NBC application was suggested.

Use of geoinformation technologies for otpimized distribution of stations of atmospheric air quality monitoring

The article deals with possible applications of modern geographic information systems for optimized distribution of stations of atmospheric air quality monitoring. Due to the fact that estimation of atmospheric pollutant concentrations is a reason for decisions to improve air quality, costly measures to protect the atmosphere and monitoring effectiveness of these actions, atmospheric air quality indicators, and therefore the proper distribution of monitoring stations, are of great importance. Results of model calculations of atmospheric air pollution, which have been recently developed in our country, in combination with GIS solutions, should be used for optimized distribution of stations of atmospheric air quality monitoring. One of the major factors of objective estimation of urban atmospheric air quality is proper reference of industrial and transport pollutant emission sources to the city’s topographic base (both in citywide and local coordinate systems), as well as distribution of stations of atmospheric air quality monitoring and selection of high-priority pollutants for a particular city district. Some recommendations for monitoring stations distribution and pollutants selection based on the GIS analysis of spatial distribution of maximum ground level concentrations of pollutants are given.

Socio-economic potential of large-scale projects to develop offshore oil and gas: risks and stakeholder expectations

  The development of the Arctic shelf is a strategic long-term objective of the energy development of the Russian Federation. At the present time, resource and economic potential of offshore oil and gas development projects is huge. However, it is constrained by the complexity of developing offshore oil and gas resources due to climatic, geological and technological conditions. In addition, the current unstable situation with world oil prices is also a constraint on largescale involvement in the industrial development of offshore oil and gas resources.  The aim of the research is to determine socioeconomic potential of large-scale projects to develop oil fields in the Arctic shelf of Russia.  The article presents the peculiarities of developing offshore fields, which are characterized by severe climatic conditions, high environmental risks, unique technological solutions, lack of infrastructure in coastal areas. A comparative analysis of projects to develop land and shelf is performed. The regional authorities’ and businesses capability of implementing large-scale projects to develop offshore fields on economic, social and environmental criteria is identified. The positive and negative effects of socio-economic development of the territory implementing projects of hydrocarbon field development are evaluated. A schematic diagram of the socio-economic potential of hydrocarbon resources development projects reflecting the opportunities and risks of such projects from the perspective of key stakeholders is developed. A set of strategic objectives to successfully implement projects in the Arctic shelf of Russia are proposed.  The findings of the research can be used by the departments of energy, industry and mineral resources in the preparation of long-term strategic development programs for the oil and gas industry.
