An Establishment of Dependencies of Mutual Influence of Geological and Mining Factors on the Stress-Strain State of the Rock Mass
Authors: Shurygin D N , Vlasenko S V , Turbor I A 
Published: June 2019

AbstractThe production activity of the coal mining industry is accompanied by the involvement in the development of deposits, which are characterized by a complication of mining and geological conditions at a depth of 1500 m. The increase in mountain pressure at great depths leads to a decrease in the efficiency of the use of complex mechanized technologies of coal mining. This is due to the imperfection of the technologies of fastening and control of mountain pressure. The existing schemes of movement of mechanized supports were developed for use at depths up to 800 m and do not take into account the features of geomechanical processes in the rock mass at depths of more than 800 m. In addition, the known technologies of fastening and management of the roof do not provide the necessary speed of fastening of the treatment face at high speeds of moving longwalls, thereby causing the formation of large undefended areas of the direct roof and increasing the probability of dumping in the bottom-hole space of longwall.
Increase of Efficiency of Extinguishing of Rock Dumps on the Surface of Coal Mines
Authors: Versilov S O , Vil’bitskaya N A , Kurdashov V M 
Published: June 2019

Abstract
The most effective technical solutions have been those that provide for the supply of substances used for extinguishing to the combustion zone of the rock dump. When quenching rock on the rock dump is proposed injection (blowing) in a dry extinguishing agent, represented by crushed vermiculite (hereinafter referred to as the extinguishing agent), in pure form or in a mixture with alkaline substances. The problem of developing methods of extinguishing rock dumps, characterized by low cost and high efficiency, in the absence of additional environmental pollution is very relevant. The technology of suppression of waste rock dumps include the injection of suspended particles of vermiculite in contrast to the clay slurry or solution (suspension) of antipyrene. This allows to penetrate into the surface layer of the middle and upper part of the blade and insulate its lower part with non-combustible material.
The Pulsed Electromagnetic Field of Polarizable Conductive Plate and Its Integral Characteristic When Excited by a Vertical Electric Dipole
Authors: Nim Y A , Gogoleva L P , Illarionova M G 
Published: June 2019

Abstract
We considered direct problem of pulsed electrical prospecting, which is based on approximation model of a polarizable electrically conductive plate (plane S), according to well-known Cole-Cole polarization model. Vertical electric lines are used as a source and receiver of a pulsed electromagnetic field, which are relatively new receiving and generating devices in pulsed electrical prospecting and fairly easy implemented in marine search and mapping of oil and gas deposits, deposits of non-ferrous metals and other mineral and raw materials sources, especially in hard-to-reach and / or deep water areas of the World Ocean, e.g. under the ice of the North Arctic ocean, in Russian exploration areas, in rift valley of Mid-Atlantic ridge. We developed analytical model of unsteady electromagnetic field of polarized plane S, excited by a vertical electric dipole. According to the Pearson hypothesis and numerous experimental data, obtained by different researchers, the polarizability of the plate is a relatively new indicator of the oil and gas deposit, which is identified by EMF induction sign change. To increase the depth of the study, we present an analytical model of integral characteristics of the pulsed electromagnetic field of polarized plate, excited by a vertical electric dipole. In this case, the magnetic flux induction, as well as EMF, changes charge.

Authors: Yakovenko N V , Didenko O V , Safonova I V 
Published: June 2019

Abstract
The article analyses the methodological issues of the socio-ecological and economic justification for the multidimensional indicator of the quality of life of the population - the welfare index of the population. Particular attention is paid to the scientific substantiation and quantitative assessment of this index, calculated for the subjects of the Central Federal District and differing in the parameters of both socio-economic and environmental development. The proposed methodology for calculating the integral indicator of the well-being of the population will allow to assess the level of socio-economic and ecological well-being of the population living in the territory of Voronezh region, taking into account the influence of institutional factors. The index of the well-being of the population reflects such indicators as the level of social and economic development, incomes of the population, the cost of living, the quality of medical care, education, the state of the environment, security, cultural level, the level of development of small and medium-sized businesses, etc. By this method, we have obtained integral indices for 18 regions of the Central Federal District for a 5-year period (from 2012 to 2016), which allow to reveal general information about the social and ecological well-being of the studied region for a certain period. The obtained generalizing indicators can be used to assess the effectiveness of the administration of municipal entities in the field of socioeconomic and environmental policy.

Published: June 2019

Abstract
Archaeological research peculiarity is that in the process of studying the monuments are completely destroyed. Further you can use only the reporting documentation, compiled in the process of excavation. Traditionally used in archeology methods (schemes, drawings, photoes), do not give a complete picture of the monument under study. Modern technologies, such as photogrammetry, laser scanning, satellite technologies, etc., allow obtaining information about historical monuments, architecture; archaeologists in the future can recreate a visual representation of them. Archaeological research include not only excavation, but also exploration during which the discovery of new monuments occurs. Modern remote sensing technologies, as well as laser scanning technologies and others allow to realize this task more effectively.

Chemical and Microbiological Composition of Technogenic Waters in the Tailing Dumps of Krasnorechensk Ore-dressing Plant (Primorsky Krai, Russia)
Authors: Kalitina E G , Kharitonova N A , Kuzmina T V 
Published: June 2019

Abstract
Chemical composition, distribution and quantity of chemolytotrophic and heterotrophic microorganisms as well as some of their ecologo-physiological properties have been studied in the technogenic waters of tailing dumps. It has been shown that technogenic waters exhibit low values of pH (2.8 to 6.1), high mineralization (up to 5.6 g/l) and high content of trace elements. Microbiological analysis has shown that a wide spectrum of microorganisms is involved in destruction of sulfate-containing minerals. Technogenic waters of tailing dumps contain autotrophic thionic and sulfate-reducing bacteria, autotrophic and heterotrophic nitrifiers, ammonifiers, heterotrophic manganese and iron-oxidizing bacteria, saprophyte microorganisms and microscopic fungi. Thionic and sulfate-reducing bacteria were most numerous in the waters under study thus indicating the processes of sulfur bacterial oxidation and reduction in the tailing dumps. Microbiocoenosis of the tailing dumps has failed to show a high qualitative diversity. Among the thionic bacteria there were Thiobacillus thiooxidans, Th. intermedius, Th. ferooxidans and Th. acidophilus. Microscopic fungi included Aspergillus, Penicillum, Mucor. The heterotrophic saprophyte microorganisms were predominantly gram-positive Bacillus sp. The isolated heterotrophic bacteria grew at the wide temperature and pH ranges and showed high resistance to heavy metals.

Published: June 2019

Abstract
Water is one of the main raw materials in the production of most foods; on its composition and quality greatly affect the quality of the finished product. In food production, water is used as a system of potable water supply, and is extracted from underground water sources.
At the today’s highly anthropogenic water pressure purification systems in the food industry do not always cope with the difficult task of water treatment, and manufacturers are often faced with the need for additional water treatment.
In this connection, the search for new approaches to adjusting the properties and composition of the water is important. The article notes the use of ultrasonic cavitation for water treatment processes for the food industry.
Two-Level Electrostatic Filter for Fine Cleaning
Authors: Okhotnikov M V , Nusenkis A A , Maksudov D V 
Published: June 2019

Abstract
In the given paper, we consider the original design of an electrostatic filter [2], which, in addition to precipitation of unburned hydrocarbon fuel particles (soot), allows to fulfill the fine cleaning of the waste flue gases. The design consists of two parts, each of which carry out respectively a coarse and fine cleaning of the smoke passing through the filter. The application of this filter allows to solve the problem of smoke emissions in certain industries and the national economy, where until now the using of the electrostatic cleaning method encountered some difficulties and was unsufficient. The compact construction of vertical design does not require the special place for its location and can be placed as a superstructure of the working pipe or inside it. The self-cleaning system at each filter level allows to minimize the influence factor of maintenance personnel on the work process, improves the safety level and increases the service life of the cleaning system between current repairs.
Water Treatment and Disinfection by Natural Solar Radiation in the Ferrous-Persulfate System
Authors: Garkusheva N M , Popova S A , Matafonova G G 
Published: June 2019

Abstract
The simultaneous treatment and disinfection of natural water and municipal wastewater using solar-enhanced Fenton-like process was studied. Using herbicide atrazine and bacterium Escherichia coli as model pollutants, the kinetics of separate and simultaneous processes of destruction and inactivation in different aqueous matrices (deionized water – DW, lake water – LW and wastewater – WW) were studied in the ferrous-persulfate system, activated with natural solar radiation {Solar/Fe2+/S2O8
2−}. It was found, that the presence of bacterial cells inhibited the rate of atrazine destruction in all water types, decreasing the pseudo-first-order rate constants by one order of magnitude. The accumulated solar doses (QUVA) for 90% atrazine removal from DW, NW and WW were 5.2, 5.7 and 9.2 kJ/L, respectively. By contrast, the presence of atrazine in NW and WW did not affect negatively on the E. coli inactivation rates. Inactivation of 95% cells was achieved (∼1.5 log reduction) at doses QUVA of 4-6 kJ/L, that is comparable with the literature data on E. coli inactivation in other oxidation systems. The combined method of simultaneous destruction of micropollutants and inactivation of microbial pathogens was proposed by using natural solar radiation in the ferrous-persulfate system.
Geochemistry of Rare Earth Elements in Volchansky CO2-Rich Mineral Water and Mineral Precipitations (Sakhalin Island, Far East of Russia)
Authors: Bushkareva K Yu , Chelnokov G A , Bragin I V 
Published: June 2019

Abstract
Distribution and abundance of rare earth elements in Volchansky Spa of CO2-rich mineral waters and REE fractionation during the formation of Fe2O3 precipitates on the Sakhalin Island (the Far East of Russia) were studied. The main common features of waters are Na-Cl-HCO3 hydrochemical type, high total dissolved solids (5.4-6.5 g/L), a slightly alkaline pH (6.4-6.5), and reduced conditions (Eh from -181 to -110 mV). The NASC-normalized patterns of groundwaters are characterized by HREE enrichments, negative Ce and positive Eu anomalies. The explanation for the HREE-enriched pattern is that the HREEs form stronger complexes with ligands in solution than do the LREE. Mineral precipitates are presented by Fe-oxides and ΣREE concentrations significantly higher compared to those of the original waters. The slight negative Ce and positive Eu anomalies are also found in the precipitates and these values are very similar to those of the original CO2-rich waters. It is point out that mineral precipitates are unfractionated or slightly fractionated in comparison to the mineral waters.

Authors: Akmaykin D A , Grinyak V M 
Published: June 2019

Abstract
The problem of marine traffic safety is discussed in this paper. The problem of ships path planning taking into account heavy weather conditions (sea waves) along the route is considered. As a metric characterizing the safety of traffic, a well-known storm diagram of ships at a passing wave is used. According to it, the level of danger is determined from the data on height and wavelength. The route is formed as a result of solving the problem of finding the shortest path on a weighed graph. As a source of meteorological data, satellite monitoring information is used. It is shown that in spite of the roughness of the initial data, they are able to give a practical solution for choosing the trajectory of the vessel’s motion. The work is accompanied by the results of full-scale experiments. The results of the assessment of the vessels safety and path planning in the waters of the Sea of Japan are presented.
