INFLUENCE OF HYDRO AND LITHO-DYNAMIC FLOWS ON THE CHARACTER OF MODERN EROSION DIVISION OF TERRITORIES

Posted in 2019, Issue № 10(88) October 2019, SCIENCES ABOUT THE EARTH | 0 comments

The article considers the problem of identifying the areas of increased denudation on the earth’s surface. Uplifting areas of the same rank are associated with them. The signs of distinguishing denudation areas, features of their structure and the nature of their division are presented. The boundaries of such regions are zones of stress release, potential discontinuities of terrestrial matter of different ranks, where systems of relatively independent (parallel with a shake of 45°) hydro- and lithodynamic flows function. The boundaries of denudation areas of three ranks are shown within the territories of the Volga-Ural and Caspian oil and gas provinces. Obtained information on the areas of denudation can be used for identifying potentially dangerous places where the restructuring of hydro- and lithodynamic flows of different ranks and the intensification of erosion processes are possible.

LANDSCAPE OF THE MONGOL-SIBERIAN REGION AS A RESULT OF INTERACTION OF EXTERNAL AND INTERNAL EARTH PROCESSES

Posted in 2019, Issue № 10(88) October 2019, SCIENCES ABOUT THE EARTH | 0 comments

The morphostructural features of the Mongol-Siberian region are of great interest when it comes to the study of the dynamics of neo-tectonic development, a significant contribution to which is made by modern vertical and horizontal movements. In this work, the geo-information analysis of a digital elevation model is carried out, and areas of sedimentation and denudation are highlighted. The spatial configuration of the selected regions is the result of the complex interaction of the Earth’s hard shell and its atmosphere. The mass volume generated in the areas of drift and accumulation characterizes the complex structure of the exogenously active layer, which is affected by a complex of exogenous processes. The results of the surface analysis allow, to a first approximation, estimating the ratio of the thickness of the lithosphere and asthenosphere in areas with different conditions of sedimentogenesis.

ON EVOLUTION OF PARAMETERS OF THE LEVEL SURFACE OF EARTH

Posted in 2019, Issue № 8(86) August 2019, SCIENCES ABOUT THE EARTH | 0 comments

The article discusses the evolution of the parameters of the level surface of the Earth based on the formulas of the Jacobi dynamical system, i.e. problems of actively gravitating centres. Mathematical expressions and numerical values for evolution are obtained: the radius of the vector of the level surface of the Earth, gravity on this surface, average compression, as well as compression of the northern and southern hemispheres of the Earth’s surface. Numerical estimates of the evolution of parameters were performed for –1010≤ t – t0 ≤ 1010 years of the time interval. The results obtained give reason to attribute the evolution of the main parameters of the Earth to the number of real phenomena.

COMPARISON OF THE SIMULATED PEAK GROUND ACCELERATION AT DIFFERENT SITES LOCATED CLOSE TO EACH OTHER

Posted in 2019, Issue № 7(85) July 2019, SCIENCES ABOUT THE EARTH | 0 comments

The paper considers the problem of how different the peak acceleration at the same input motion (in the form of an accelerogram) at different sites located close to each other. The results of modeling the transformation of one and the same input motion by the soil strata of two different sites are presented. The sites have a similar geological structure. The bedrock is at the same depth. Under such conditions, when designing seismic resistant objects, design engineers for emergency load combination calculations usually use the same set of design accelerograms. The simulation results presented in this article showed that the transformation of the same one input movement by the soils of closely located sites with similar geology, differs significantly.

EVALUATION ON DRILLABILITY OF MOUNTAIN BREEDS OF NONZHDANINSKOE GOLD DEPOSIT IN YAKUTIA

Posted in 2019, Issue № 7(85) July 2019, SCIENCES ABOUT THE EARTH | 0 comments

This article is aimed at estimating the drillability of mountain breeds of the Nezhdaninskoe gold deposit, which is one of the most promising sites for the extraction of precious metals in the Republic of Sakha (Yakutia).

Literary sources and references to modern scientific works describing the techniques of regulatory support of technological processes in the North, in the field of permafrost distribution, are given.

A number of objective methods for determining the drillability of mountain breeds are considered. To solve the problem, it is feasible to use the method of determining the actual drillability of mountain breeds by pilot drilling with rational values of the drilling mode parameters and types of rock-destroying tool. Experimental determination of the category of rocks by drillability according to actual data at sites of mining and tunneling works, the main material for which were the results of full-scale studies of the physico-mechanical properties of rock samples from the field, was gradually set out.

It is indicated that, in contrast to the previous work, to switch from non-standard drilling conditions to standard drilling conditions, a general correction factor was used, defined as the product of the coefficients of influencing factors. A relative indicator of the difficulty of drilling the mountain breed was adopted as a physico-technical basis for comparing mountain breeds for drillability (depending only on the properties of rocks).

Based on the conducted studies, it was shown that the assessment of the drillability of mountain breeds from the Nezhdaninskoe field with regard to non-standard drilling conditions of the field’s rock at the highest degree of difficulty will fall into the 20th category and above — extra-trench, extremely difficult to drill and 18, i.e. 2 categories below.

EVALUATION OF THE EFFECT OF DETACHED WATER OF BOTTOM SEDIMENTS AND UNDERGROUND WATER ON THE QUALITY OF WATER OF IVANKOVO RESERVOIR

Posted in 2019, Issue № 5(83) May 2019, SCIENCES ABOUT THE EARTH | 0 comments

Ivankovo Reservoir is the main source of water supply in Moscow, and due to the increasing anthropogenic load on its catchment area and the deterioration of the quality of water supplied to the Moscow canal, the problem of its contamination with heavy metals is particularly relevant. The content of Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Fe, Mn in the near-bottom water horizons, pore solutions and the solid phase of bottom sediments were measured on the reservoir in the intra-annual mode.

Studies have shown that the proportion of heavy metal reserves in the pore solution is insignificant compared to their reserves in the solid phase, but the role of the pore solution in the processes of secondary pollution of the water masses of the reservoir is not limited to the reserves of dissolved elements. Part of the elements from the solid phase of bottom sediments can pass into the pore solution and further into the water mass – thus, the transition from the sediments to the water mass is carried out in transit through the pore solution. Also, the estimates made show that neither diffusion removal nor filtration can be real mechanisms for the removal of trace elements into the water mass.

GEOGRAPHICAL ASPECT OF INTEGRATION OF PERSONS WITH DISABILITIES IN SOCIETY

Posted in 2019, Issue № 5(83) May 2019, SCIENCES ABOUT THE EARTH | 0 comments

The article deals with the integration of persons with disabilities in society. Several scientifically based measures were proposed, they could potentially contribute to the involvement of persons with disabilities in socially beneficial activities. The fact that more than 12 million people with disabilities live in the Russian Federation indicates that this problem is relevant. However, there is not yet a single term, unified for all levels of legislation defining this category of citizens. The author believes that in relation to this study, a “disabled person” is a person, in order to remove the disabilities of which, it is necessary to develop programs that allow him/her to integrate into public life of civil, social and medical institutions (taking into account the territorial features of the external living environment). For the development of such programs, it is recommended to use the problem-program approach. Within the framework of the federal target program “Accessible Environment,” it is proposed to create organizational and management clusters, taking into account the specifics of resettlement when locating objects of social and medical infrastructure, popularizing the “accessibility map” project both among people with disabilities and among the organizations serving them.
