Kuralbayev Z. Rakhimzhanova <p>The article is devoted to a model study of the process of occurrence of landslides of sedimentary rocks located on the surface of the hill. It is assumed that when the viscosity of sedimentary rocks decreases, they move down the slope of the hill under the influence of gravity. The motion of the viscous layer is described as a creeping flow of a highly viscous liquid. The study of this process was carried out by the method of mechanical and mathematical modeling, which resulted in the problem of solving a quasi-linear equation of parabolic type. To solve the mathematical problem, the finite-difference method was used; a nonlinear implicit calculation scheme was chosen, on the basis of which the algorithm for solving the problem was formulated and a computer program was developed. A numerical experiment was carried out for various possible variants; mechanical characteristics of clay rocks were taken as initial data of physical parameters. The results of the study are presented in the form of graphs and tables.</p> 2021-02-16T00:00:00+00:00 Copyright (c) 2021 VESTNIK KAZNRTU Determination of the wetting angle of an oil core with an aqueous polymer solution 2021-02-16T10:19:25+00:00 V.G. Golubev A.S. Sadyrbaeva S.E. Baibotayeva A.M. Turebekova D.B. Amantaeva S. Zhanabai <p>In the present work, the description and results of experimental studies to determine the contact angle of wetting of an oil core with a polymer solution are given. The information on the theory of wettability of the rock and the methodology for conducting research and reference data of the Nurali deposit are provided. With an increase in the concentration of the component in the formation water, a significant decrease in the contact angle of the surface of the oil core is observed. So the hydrophobic surface of the core model, saturated with oil, with a contact angle of formation water wetting of more than 105º, after processing the core surface of 0,25% of the mass. PAA solution becomes hydrophilic, and the value of the contact angle, in the conditions of the experiment, is 75º. Based on the results of the experiments, it can be concluded that surface treatment of oil core with solutions of these components leads to significant hydrophilization of its surface.</p> 2021-02-16T00:00:00+00:00 Copyright (c) 2021 VESTNIK KAZNRTU Geoecological zoning of the territory on the degree of gravitation processes on the basis of application of GIS technologies 2021-02-16T08:29:33+00:00 M.K. Kudaibergenov <p>The issues of building a new facility or using the constructed facility are of great importance for gravitational processes, including the study and forecasting of avalanches, since the number of slopes caused by geotechnical systems and human activities that can be activated in the case of an ancient natural avalanche is increasing.</p> <p>Measures to prevent landslides are much simpler and more effective than combating them. Therefore, slope forecasting is a natural and social task. The aim of exogenous geological, in particular, moving trends, is to determine the quantitative and qualitative characteristics of the geological environment in terms of space and time under the influence of natural and anthropogenic factors, as well as to assess the degree of their risk of engineering land and agricultural land.</p> <p>Forecasting methods for territories with different natural and technological conditions are of great importance, therefore, the problem is solved by a systematic approach to research, and geotechnical forecasting is selected based on the period of economic development of the territory, the size of the projected territory and the time interval. To avoid the negative consequences of landslide processes, it is necessary to predict the situation at the earliest stages of economic development.</p> 2021-02-16T00:00:00+00:00 Copyright (c) 2020 VESTNIK KAZNRTU Foreign experience of rehabilitations of the old solid waste landfills 2021-02-16T08:46:41+00:00 A. Ospanbayeva S. Wang <p>The paper introduction is starts with facts regarding dumpsites in the modern world and rehabilitation. Then, a conceptual framework of characteristics of the old landfills is discussed and the main examples of treatment methods are given. The main part of the paper presented, that many types of resources can be extracted from old landfills and able to use as a new material later. According to this introduction the old landfills are beneficial part of using in the future.</p> 2021-02-16T00:00:00+00:00 Copyright (c) 2021 VESTNIK KAZNRTU Application of pattern recognition systems for automation of the process of plant objects classification and deviations identification in plant development 2021-02-16T08:55:25+00:00 G. Kim A. Demyanenko V. Tyukanko <p>To automate many agricultural processes, classification (sorting) of plants by species and by other quantitative and qualitative characteristics is important. Examples include automatic weeding or spot spreading of fertilizers or herbicides. In addition, the timely and accurate determination of deviations in the development of plants, including the diagnosis of their diseases, plays an important role in preventing a decrease in the yield of agricultural products. To solve these problems, it is necessary to automate as much as possible all processes in agriculture by methods based on machine learning and, in particular, on methods of pattern recognition. Currently, deep learning is widely used in image processing. The article provides examples of the successful application of pattern recognition methods in agriculture and discusses various methods of machine learning and deep feature extraction that adapt deep learning models to the problem under consideration.</p> 2021-02-16T00:00:00+00:00 Copyright (c) 2021 VESTNIK KAZNRTU About the influence of tectonic features of gold deposits on their engineering-geological conditions 2021-02-16T09:04:50+00:00 A.B.
