Аннотация: Mining a cryptocurrency is profitable on someone’s resources. It is becoming increasing problemin the enterprise to control the operations of its infrastructure while in idle or “off-work” time. Inthis paper we present enterprise security assessment framework for cryptocurrency mining basedon Monero cryptocurrency. The framework consists from surveying power consumption on GPUmining farms and traditional desktop PCs, analysis of web resources for browser-based miningon both internal and external domain names, the handy network logs analysis tool based on theregular expressions. While there had been significant difference between GPU and traditionaldesktop PC’s power consumption, computational ratio of the idle PCs after working time remainsquestionable. In the browser-based cryptocurrency mining, there were no data on public domains,however there had been a possibility for using the private domain names, thus further researchand different tools are required. In the network analysis, there were not enough evidences on thenetwork mining, and this leads to the different research question that attackers may use proxytechniques to bypass traffic filtering and network analysis.

Аннотация: The data on accumulated mining waste in the territory of Kazakhstan are presented. Their processing has become very important in our time. The structure of surface-modified carbon materials with a grafted layer is given. New modified carbon sorbents were obtained, oleum was used as a modifying agent. It was revealed that the capacitive characteristics of the modified sorbent are significantly higher than that of the original one, which will make it possible to more efficiently extract the metal ion from wastewater and technogenic formations. Sorption is an effective method of extracting valuable components from wastewater and man-made formations. This method allows you to recover valuable substances with a high degree of wastewater treatment, which can be purified to the maximum permissible concentration of pollutants and then used in technological processes or in recycling water supply systems. Processing involves ores characterized by a low content of valuable components, fine dissemination and similar technological properties of minerals. The existing technologies for the development of minerals make it possible to use only a small part of the valuable mineral mass extracted from the subsoil, and the rest forms waste, which, as it accumulates and is stored, becomes one of the most significant factors of anthropogenic changes in the environment.

Р•-mail: SSA2704@mail.ru NUMERICAL MODELING OF THE STRESS-STRAIN STATE OF THE KURZHUNKUL OPEN-PIT MINE Abstract. The stress-strain state of rocks is one of the main factors that determine the magnitude and nature of rock pressure, on which the safety of deep open pit development depends. When conducting mining operations, it is necessary to understand where zones of increased principal components of normal and maximum shear stresses form. The article presents the results of numerical modeling of the stress-strain state of the Kurzhunkul pit in a two-dimensional formulation by the finite element method in the MIDAS GTS NX software package. In mathematical modeling, the stresses actually acting in the array, determined by field measurements, were taken into account. A model based on the results of modeling is presented, which can be used to predict changes in the maximum gradient of horizontal stress with an increase in the depth of mining of the Kurzhunkul open-pit mine. Based on the results of the modeling of the sides in the southeastern north-western directions, areas were identified where there is an unfavorable effect of the maximum shear stresses on the side rock mass and the maximum shear stresses (н µнјЏн µнјЏн µнјЏн µнјЏн µн±љн µн±љн µн±љн µн±љн µн±Ћн µн±Ћн µн±Ћн µн±Ћн µн±Ћн µн±Ћн µн±Ћн µн±Ћ) may exceed the shear strength. Also, an assessment of the influence of the main components of normal and maximum shear stresses on the stability of the near-rock pit rock mass is given. It has been determined that the geomechanical state of the sides of the Kurzhunkul open-pit mine is characterized by the action of low compressive stresses. The values of the maximum compressive stresses vary from 5.52 MPa to 14.25 MPa, increasing from the day surface to the bottom of the open pit. The minimum component of the principal stresses varies from 0.70 to 9.4 MPa.

Key words: stress-strain state, pit, distribution of principal stresses, rock mass stability, a two-dimensional numerical model. Introduction. The problem of predicting the tectonic effect on the stress state of the rock mass is important in geomechanics today. If the natural stresses in the sides of the pit slope are high and exceed the strength of the rock mass, then its deformation occurs and large zones of weakened rocks are created, which can then collapse under the influence of their own weight [1, 2]. Based on the results of field studies, it was determined that the stress-strain state of the rock masses of the Kurzhunkul pit was attributed to the gravitational-tectonic type [3]. The stability of quarry walls in rocky tectonically stressed rocks is determined, first, by the parameters of the stressstrain state, structural disturbance, and strength characteristics of the rock mass. Materials and methods. To substantiate the rational design parameters of the Kurzhunkul opencast mine, calculations were performed to estimate the stress-strain state of the rock mass in a two-dimensional (2D) formulation by the finite element method using the MIDAS GTS NX software package. Finite element method (FEM) calculation in MIDAS GTS NX can be conditionally divided into the following stages: - setting the computational domain with the selection of characteristic areas and mechanical properties for the selected areas; предела прочности РЅР° СЃРґРІРёРі. Также приведена оценка влияния главных компонент нормальных Рё максимальных касательных напряжений РЅР° устойчивость прибортового массива карьера.

Аннотация: Мақалада Қазақстан мен Өбекстан арасындағы экономикалық байланыстың жаңа тәсілдері талқыланып, қазіргі кезеңдегі екіжақты экономикалық қатынастардың дамуына баға берілген, Өзбекстан президенті Шавкат Мирзиеевтың жаңа сыртқы саяси бастамаларының екіжақты қарым-қатынастарға тигізер әсері туралы баяндалған. Авторлар мақалада 2000 жылдардан бастап қазіргі кезге дейінгі екіжақты экономикалық қатынастардың қысқаша эволюциясын ашып көрсеткен. Авторлар Өзбекстанның бірінші басшысы Ислам Каримов және Өзбекстанның қазіргі Президенті Шавкат Мирзиеевтың саясатын салыстыра отырып, бұл кезеңде Орталық Азиялық интеграцияның даму деңгейін сипаттаған. Авторлардың пайымдауынша, Қазақстанның Өзбекстанға болған қарым-қатынасы әрқашан ашық сипатта болып, интеграцияға бағытталған. Алайда, Өзбекстанның акциздік саясаты, Каримовтың жүргізген саясатының нәтижесінде Қазақстан мен Өзбекстан арасындағы қарым-қатынас өзара түсіністік, достық сипатында болып, өзара сауданың көлемі баяу дамыды. Мысалы, Каримов басшылығында 2000 жылдары екі елдің жылдық тауар айналымы 295,4 млн долларды құраған болса, 2021 жылы Мирзиеевтың бастамасымен 1 қаңтардан бастап Өзбекстан тасымалданатын тауарларға қатысты акциздерді қолдануды тоқтатқаннан кейін 4 айдың ішінде қаңтар-сәуір айларындағы екіжақты тауар айналымы 1,2 млрд долларды құрады. Бұл 2000 жылдармен салыстырғанда шамамен 12 есеге көп. Авторлар тек екіжақты сауда айналымының динамикасын ғана емес, қазіргі кезеңдегі жүзеге асырылып жатқан екіжақты бірлескен жобаларды, көлік-логистика саласындағы жетістектерді оң бағалайды.The article discusses new approaches to economic relations between Kazakhstan and Uzbekistan, assesses the development of bilateral economic relations at the present stage, tells about the impact of new foreign policy initiatives of the President of Uzbekistan Shavkat Mirziyoyev on bilateral relations . In the article, the author reveals a brief evolution of bilateral economic relations from the 2000s to the present. Comparing the policy of the first head of Uzbekistan Islam Karimov and the current President of Uzbekistan Shavkat Mirziyoyev, the author described the level of development of Central Asian integration at this stage . The author believes that Kazakhstan's relations with Uzbekistan are always open and aimed at integration . However, as a result of Uzbekistan's excise policy pursued by Karimov, relations between Kazakhstan and Uzbekistan were of the nature of mutual understanding, friendship, and the volume of mutual trade developed slowly . For example, if in Karimov's leadership in the 2000s, the annual trade turnover of the two countries amounted to $ 295 .4 million, then in 2021, at Mirziyoyev's initiative, for 4 months after Uzbekistan stopped applying excise taxes on transported goods, the bilateral trade turnover for January-April amounted to $ 1 .2 billion . This is about 12 times more than in 2000 . The author positively assesses not only the dynamics of bilateral trade turnover, but also the bilateral joint project being implemented at the present stage, achievements in the transport and logistics sphere .
