Authors: Gorlenko N V , Timofeeva S S 
Published: April 2020

Abstract
Oil has become an integral part of our world, if we look around and think about it, we will see familiar objects made thanks to this wonderful natural hydrocarbon. Now everyone is used to criticizing oil and everything connected with it, but let us look at it in a new way. Oil and natural gas are familiarly associated with fuel, but this is only a small part of what they are capable of: glue, plastic, polymeric materials, fabrics, varnishes, cosmetic and medical materials. Indeed, it has become an indispensable material. Let us consider the environmental impact associated with the extraction of this wonderful and irreplaceable material. Nevertheless, oil and gas production inflicts enormous damage on the ecological situation in the regions of oil and gas provinces. To extract “black gold” one has to go a long way that sometimes lasts for decades, the process of field exploration and development is very cost intensive. New technologies in exploration help enterprises reduce costs, but still these stages remain expensive. Enterprises try to minimize their costs and expenses at all stages. In this paper, we will consider the consumption of water resources and the total loss of aquatic biological resources of four fields in the Lena-Tunguska oil and gas province: the Yarakta, Iktekh, Markovo and Dulisma fields. The assessment was carried out at the stage of the construction and development of the fields.

Abstract
The specific heat is an important characteristic of soils at their application as the bases of buildings and engineering structures. The article presents the experimental data on specific heat of the Amginsky deposits clay soil in the Republic of Sakha (Yakutia) in the range from sorption humidity to upper limit of plasticity obtained by the differential scanning calorimetry Sensys Evo TG-DSC. The specific heat measurements were carried out on samples of clay soil taken directly from the deposit and samples of the same soil, but previously cleaned of impurities. It is established that for clay soil the dependence of the specific heat capacity on humidity is not monotonous but has a maximum
Modern Methods and Tools for Determining Drillability and Blastability of Rocks
Authors: Kosolapov A I 
Published: April 2020

Abstract
Often in practice, the coefficients of Protodyakonov scale of hardness f are not established based on objective measurements that are very laborious, but by visual degree and rock family type, which naturally significantly reduces the accuracy of calculations.
In this regard, it is proposed to obtain information on the physical-mechanical properties of rocks directly from rigs during drilling, based on the energy characteristics of this process; its main characteristic is the specific drilling energy, i.e., the energy required to destroy a unit of rock during drilling.
For a quantitative assessment of the rock strength as resistance to mining - technological destruction - prof. M.M. Protodyakonov [2] proposed the coefficient of hardness f, in the first approximation, it is proportional to the rock break-down point under compressive load. The scale of hardness was developed, according to which all rocks are divided into ten categories. Many post-Soviet engineers use this coefficient. Since the coefficient of hardness mainly reflects only fracturing under compressive loads, and in real conditions tensile and shearing forces are often used, it becomes necessary to introduce other indicators to assess the properties of rocks.

Authors: Korkin S E 
Published: April 2020

Abstract
The present research is based on recording method of soil temperature surveys and underlying quaternary deposits. All surveys were conducted over two key areas as follows: first area is located within the boundaries of Northern taiga landscapes of Western Siberia (Siberian ridges - thermal wells 1, 2, 3 и 8); the second area belongs to middle-taiga landscapes of Western Siberia (Sredneobskaya lowland – thermal wells 4, 5, 5a, 6, 7). All temperature data obtained within the boundaries of key areas was measured by thermal logger DS1921G-F5 for the depths within range of 20 cm, 40 cm, 60 cm, 1 m and by another thermal logger DS1921Z-F5 for the depths within range of 2 m, 3 m, 4 m, 5 m, 6 m, 8 m. The average annual temperature of years 2015-2016 observation period of thermal well 5a (technogenic site) is 8,3 °C for the whole range of depths and considered to be higher by 3,8 °C then average annual temperature recordings of thermal well 5 and, at the same time, considered to be higher by 4,2 °C then recordings of thermal well 6, which belongs to natural bog landscape. The abovementioned data was confirmed by recordings of years 2015-2016 with the difference of 4,8 °C for thermal well 5 and 3,7 °C for thermal well 6. A slightly higher temperature was indicated for the soils underlying anthropogenic objects in correlation to natural, not induced by man-made impact biogenic soils and this fact affects natural processes. The results of the present research indicates that the most warm soils are illuvial-ferrugenous. This type of soil warms up quite well at the top portion of the profile (horizons O, E) and stating from the depth of 40 cm the temperature goes down to 0 °C. Black dirt oligotrophic soils are having good warming up abilities. It can keep and increase positive temperature with increasing depth. A slight temperature decrees refers to level of paludal-lacustrine basin of 30–40 cm.. are having good warming up abilities and can keep positive temperature at depth. Alluvial soddy soils of the first key area (floodplain of the Gluboky Sabun River) are considered to be the coldest soils based on the results of the conducted observations. The annual average temperature in this type of soil for the time period of years 2010 to 2017 is about1,2 °C.

Published: April 2020

Abstract
Assessment of soil pollution with chemicals in certain districts (zones) of the city of Kazan was performed according to the data of the social-hygienic monitoring of the FBHI “Center of Hygiene and Epidemiology in Republics of Tatarstan” for the period of 2010 -2016. The indices of complex assessment of soil pollution with heavy metals (HM) and oil products in the zones under study did not exceed the established regulations. The results showed uneven distribution of pollutants on the territory of the city zones. The 3-rd zone (the Vakhitovsky district) is different, there the major contribution to the total risk level is made by lead (Pb) – 51.4%, cadmium (Cd) - 36.9%, mercury (Hg) – 3.53%, oil products, and copper (Cu) – 2.6%. The level of non-carcinogenic risk for the health of the child population aged 3-6 years old with application of regional exposure factors (THI 1.0 and less) corresponds to the target risk level. The maximum contribution to THI is caused by the dermal route of the oil products’ entry (from 94.0 to 98.9 %). Ranking of the city territory according to the total hazard quotient with the account of all routes of the chemicals’ entry identified two zones ranking first in the risk level: the 2-nd zone (the Sovetsky district) and the 3-rd zone (the Vakhitovsky district). The results indicate the necessity of revising the approaches to assessment of possible health risks associated with oil hydrocarbons on the basis of new scientific data.

Abstract
The paper discusses the problems of cleaning technological pipelines and tanks to restore the capacity and useful volume capacity of oil pumping stations. The world experience of using chemical reagents for cleaning oil pipelines from asphalt-resinous paraffin deposits is considered, the disadvantages and advantages of the method are determined taking into account the restrictions that exist at the facilities of the main oil pipeline transport. The analysis of the results of experimental laboratory studies and pilot tests of the chemical washing technology at the existing facilities of Transneft PJSC is presented. Recommendations are given on improving the technology to reduce the consumption of chemicals and time costs. Particular attention is paid to the shortcomings and features of the use of hydrocarbon solvents for cleaning technological lines from pipes of small diameter and large tanks. The expediency of an additional physical effect is substantiated to increase the efficiency and rate of destruction and removal of hard-to-remove deposits, for which the use of ultrasonic resonators providing flow homogenization and dispersion is proposed.
Thermo-oxidative Reactivation of Active Coal Used in Streptomycin Production
Authors: Simkin Y Y , Lemeshevsky A I , Karnaukhova E V 
Published: April 2020

Abstract
The spent active coal of streptomycin production contains on its surface the remains of inorganic acids, organic-originated alcohols and waste products, spores, mycelium of Streptomyces griseus, which after entering the environment with wastewater cause a significant harm to it. The recycling of that coal and its reuse betters the economics of production and prevents harmful impurities from entering the environment together with that coal. Here it is demonstrated that thermal heating up to 300 °C allows to increase the adsorption activity according to methylene blue test and pH of aqueous extract of recycled sorbents close to the regulatory values, which raises the possibility of their re-use in the production of streptomycin. The raise of temperature more than 300 °C leads to decomposition of high-molecular organic substances on the surface of a coal with subsequent formation of a carbon film which covers the adsorbing pores and worsens the adsorption properties of active coal. After treatment with water vapor at a temperature of 800 °C the characteristics of the active coal meet the regulatory requirements of streptomycin production. Rational way to dispose an active coal which lost its recyclability is a burning at temperatures more than 800 °C. This completely neutralizes all the harmful impurities.

Published: April 2020

Abstract
The steady increase in the price of gold in the world market causes increased interest of domestic and foreign investors not only in the traditional and long-known gold-bearing regions of Russia, but also in new territories where valuation works for gold have been actively carried out recently. One of such territories in the Polar Urals is the Riphean-Ordovician folded frame of the Precambrian Kharbey crystalline massif located in the Sakmar-Lemvinsky structural and facial zone within the river basins Grand Paypudyna river and Kharbey river. The gold mineralisation of Kharbey area and its ampelshorskaya zone is associated with the development of the black shists formation, with the stratiform type of gold mineralization characteristic. Another important feature of this area is the massive development of heterogeneous mineral veins, some of which may be gold-bearing.

Published: April 2020

Abstract
In our country, particular attention is paid to the safety of operating hydraulic structures, operational reliability of which is an integral part of the overall security of the Russian Federation. The security and energetic efficiency of hydraulic structures is regulated by the Town Planning Code of the Russian Federation, federal laws, and the code of rules “Hydrotechnical Structures. Key Points” [1-4]. Recommendation on the implementation of federal state construction supervision by officials of Rostekhnadzor (Federal Environmental, Industrial and Nuclear Supervision Service of Russia) during the construction and reconstruction of hydraulic structures are contained in methodological recommendations [5, 6]. Investigation of the operational reliability of soil hydraulic structures issue and the development of measures to extend the established term of their operation is a pressing challenge. To solve this challenge, the technical examination of hydraulic structures from soil materials, which allows us to assess the state of strength properties and the stress-strain state of dams, dikes, etc. is of great importance.
The vast majority of soil dams are checked only visually, which does not allow to reliably assess their strength properties. To determine the development of infractions in the body of the dam, to determine the amount of washed soil at hydraulic structures, etc. geodetic methods of research can be used, which, compared to the visual methods, are more accurate.
In order to determine the capabilities of geodetic methods for determining the volume of washed soils at hydraulic structures, the authors carried out experimental work to determine the volume of washed soils of the coast protection structure “Gluhaya Damba” (“Deaf Dam”) in the ash-disposal area near Zaimskiy island in the Omsk region.

Authors: Sverguzova S V , Shaikhiev I G , Hunade L 
Published: April 2020

Abstract
In this paper, we consider the possibility of extracting Fe3+ ions from aqueous media with native and modified peanut peel. Peanut peel is an unclaimed waste generated after extracting peanut kernels and at present, in most cases, it is directed to burning. Meanwhile, the peanut peel is a cellulose-containing material with a branched pore system and a large specific surface, which determines the prerequisites for using it as a sorption material in water treatment processes. Before use, the peanut peel (PP) was crushed and dispersed using a standard set of sieves to obtain fractions of particles of various compositions. Adsorption isotherms are plotted and the maximum isotherm (Amax) was determined, which was 1.52 mmol/g or 85.7 mg/g for the initial material and 1.6 mmol/g or 96.0 mg/g for burnt at 350 °C.
Great Depths in the Crust - Peculiarities of Hydrocarbon Generation
Authors: Kerimov V Yu , Kosyanov V A , Mustaev R N 
Published: April 2020

Abstract
The purpose of research is to identify the features of hydrocarbon generation at great depths of the Earth. It is shown that all the conditions necessary for generation of oil and gas are kept at great depths in the crust in the zones of high pressures and temperatures. However, generation of hydrocarbons in such settings significantly differs from the processes of oil and gas formation at shallow depths. A complex system of mutual thermobaric factors and distribution of the oil and gas potential at great depths was revealed: the start of generation and the phase distribution of hydrocarbons in the section are largely affected by settling of abnormally high pore pressure, as well as by paleotemperatures that could differ considerably from the present-day ones depending on the age of deposits. It is shown that different thicknesses of catagenetic zones are related to the kinetic rate of oil and gas generation, which depends on the type of kerogen, the gradient of temperature change, pressure, lithology, and hydrogeological conditions of the host rocks, the sedimentation rate, and other factors.

Published: April 2020

Abstract
The Republic of Sakha (Yakutia) having a vast territory located in various climatic zones and a developed network of water bodies exposed to a wide range of natural emergency. The spring-summer floods are the most characteristic. They cause extensive flooding of territories, facilities and infrastructure. This article draws attention to one of the main problems of the natural emergency in the Republic of Sakha (Yakutia). At ice drift on some parts of the river ice gorge is formed and causes flooding of nearby settlements and this brings huge social and material damages to the population and economy of the Republic. The use of satellite information and GIS in emergency situations (ES) allows to perform cartographic modeling of dangerous situation conditions. Cartographic modeling is necessary as a tool to visualize the situation and to simulate its changes. Using satellite images of Landsat 8, the zones of a settlement flooding are revealed and according to them the map of zones of the district subject to spring flood is created in the ArcGis program. Damage calculation is performed with the use of the «Guideline on the assessment of damage caused by large-scale flooding in the regions of the Far Eastern Federal district», approved by the Ministry of emergency situations in Russia. The decree of the Russian Federation Government on prevention and liquidation of emergency situations and consequences of natural disasters is used to compensate the damage caused to the victims of floods

Published: April 2020

Abstract
This research seeks to substantiate the need for special psychophysical recreation areas (closed greenspaces) at international and regional airports. To that end, the researcher has: studied the medical and psychological impact of flight on human condition; considered the creation and maintenance of greenspaces from the standpoint of botany; analyzed the existing closed greenspaces at airports, their pros and cons; proposed solutions to identified problems; analyzed various layouts for such greenspaces and projected the microclimate they might have; developed a concept and proposed a working model for stand-alone airport greenspace. The paper analyzes a pilot design and proposes the basic principles behind airport-based psychophysical recreation areas: special plants for better microclimate; comfortable visuals, i.e. harmonious and non-aggressive interiors; use of greenspace to mitigate the stress the airport environment subjects human beings to; airport greenspacing on the basis of space classification; layout optimization, i.e. functional zoning of greenspaces, with special areas being arranged for crew members, arriving and departing passengers, and passengers of different age groups. Spatial layouts, engineering, and designs may vary to better fit the purpose. Thus, a single closed greenspace instance may comprise multiple modules to serve different use cases. One mandatory feature is accessibility for persons with reduced mobility combined with special communication means for persons with disabilities.
