Introduction. The work is aimed at the development and justification of flotation technology of microdispersions of minerals, including gold. At traditional approach to a problem of effective extraction of particles which size does not exceed 10-30 microns, formation of flotation complex is investigated using the apparatus of thermodynamics. Such approach is rational for solving technological problems, when the completeness of collective extraction of all solids present in the aqueous phase is a necessary and sufficient condition. At flotation of ores the requirement of completeness of extraction of valuable components is supplemented by a condition of selective separation of minerals. Materials and methods. The main method of research is a theoretical analysis of the hydrodynamic interaction of polydisperse particles, laboratory scale flotation experiments performed on a sample of gold-bearing ores with high content of gold microdispersions using carrier minerals. Results. It is shown that the hydrodynamic resistance force acting on a solid particle from the side of unrestricted liquid flow is composed of two components. The first one is the pressure force directed along the normal to the surface of the particle, and the second one is the friction force directed along the tangent to the surface of the particle. The influence of hydrodynamic force acting on the particle from the side of liquid bounded by the wall can be accounted for by correction, in the form of the ratio of particle size to its distance to the wall, which is less than unity. Discussion. It is shown that the hydrodynamic resistance force acting on a solid particle from the side of unrestricted liquid flow is composed of two components. The first one is the pressure force directed along the normal to the surface of the particle, and the second one is the friction force directed along the tangent to the surface of the particle. The influence of hydrodynamic force acting on the particle from the side of liquid bounded by the wall can be accounted for by correction, in the form of the ratio of particle size to its distance to the wall, which is less than unity. Conclusion. In flotation with the use of carrier minerals, it is necessary to take into account the influence of a large particle – the wall – on the motion of the liquid phase and small particles. The effect of the wall on the motion of a single fine solid particle in the case of the flowing of an arbitrarily shaped particle moving parallel to the wall has been evaluated. The results obtained can also be used to assess the effect of a group of particles in a fluid, provided that the interaction between the particles can be neglected. The hydrodynamic drag force acting on a solid particle from the unrestricted fluid flow is composed of two components. The first one is the pressure force, which is directed along the normal to the surface of the particle, and the second one is the friction force, which is directed along the tan
简介。这项工作旨在开发和论证包括金在内的矿物微分散浮选技术。在有效萃取粒度不超过 10-30 微米的颗粒的传统方法中,使用热力学装置对浮选复合体的形成进行了研究。这种方法对于解决技术问题是合理的,因为水相中存在的所有固体的完全集体萃取是一个必要和充分的条件。在矿石浮选过程中,矿物的选择性分离条件补充了完整提取有价值成分的要求。材料和方法。研究的主要方法是对多分散颗粒的流体动力学相互作用进行理论分析,并利用载体矿物对含金量高的微分散金矿石样本进行实验室规模的浮选实验。结果显示实验表明,从液体流动不受限制的一侧作用在固体颗粒上的流体阻力由两部分组成。第一部分是沿颗粒表面法线方向的压力,第二部分是沿颗粒表面切线方向的摩擦力。流体动力的影响来自于以壁为界的液体一侧,可以通过校正的形式来考虑,校正的形式是颗粒大小与其到壁的距离之比小于 1。讨论。研究表明,从液体流动不受限制的一侧作用在固体颗粒上的流体动力阻力由两部分组成。第一部分是沿颗粒表面法线方向的压力,第二部分是沿颗粒表面切线方向的摩擦力。可以通过校正的方式来考虑从被壁包围的液体一侧作用在颗粒上的流体动力的影响,校正的形式是颗粒大小与其到壁的距离之比小于 1。结论在使用载体矿物进行浮选时,有必要考虑大颗粒--壁--对液相和小颗粒运动的影响。我们评估了在任意形状的颗粒平行于壁流动的情况下,壁对单个细小固体颗粒运动的影响。所得结果也可用于评估流体中颗粒群的影响,前提是颗粒之间的相互作用可以忽略不计。在不受限制的流体流动中,作用在固体颗粒上的流体动力阻力由两部分组成。第一部分是沿颗粒表面法线方向的压力,第二部分是沿颗粒表面切线方向的摩擦力。流体动力作用在颗粒上的影响来自以壁为界的流体一侧,可以通过修正来解释,修正的形式是颗粒大小与其到壁的距离之比小于 1。因此,壁面的存在会导致壁面和颗粒之间的非稳态流体流动接近稳态的速率增加,从而导致从壁面边界流体一侧作用在颗粒上的流体动力阻力减小。对称膜和润湿膜变薄和突破动力学的理论分析和实验研究结果证明,通过在浮选系统中引入载体矿物,颗粒微分散浮选模式的效率很高。最好使用从矿石中提取的粗精矿作为载体材料。在这种情况下,主要浮选前沿可被视为理想的置换装置,在矿物流混合时,提取颗粒的分布对浮选速率的影响对分离过程的技术指标的影响最小。就水的边界层的结构和性质而言,水中气泡的表面与固体疏水表面附近的水的近表面层相似。因此,气泡和颗粒在浮选过程中的相互作用是由疏水吸引力(对于疏水颗粒)和亲水排斥力(对于亲水颗粒)决定的。为此,在浮选过程中通过空气与热水蒸汽的混合物对矿浆进行曝气。

Introduction. The aim of the work is to develop a procedure for synthesizing the parameters of elastic-damping devices for shovel based on the representation of these devices in the form of additional feedbacks and optimization of the transfer functions of these feedbacks, which allows abstracting from specific methods of their implementation and making a comparative assessment and reasonable choice of device parameters. Research method. Optimization of the parameters of elastic-damping devices is carried out on the basis of using the root method for studying the characteristic polynomial of the transfer function of the additional feedback and setting the desired nature of the transient process, which is the solution of the original differential equation of motion with given roots. Results. A procedure for synthesizing the parameters of elastic-damping devices based on the representation of these devices in the form of additional feedbacks and optimization of the transfer functions of these feedbacks using root methods is proposed, which allows one to abstract from specific methods of their implementation and make a comparative assessment and reasonable choice of device parameters. Analytical dependencies are obtained, that establish a relationship between the parameters of elastic-damping devices and the quality of transient processes, making it possible to determine the effective range of these parameters. Numerical modeling of the electromechanical system of the digging mechanism of a mining excavator was carried out based on the use of its real characteristics, which confirmed the high efficiency of the proposed method for the synthesis of stiffness and damping parameters of elastic-damping devices. Currently, an experimental unit equipped with a prototype of an elastic-damping device is being created, on which it is expected to evaluate the performance and effectiveness of the proposed method for synthesizing parameters. After this, it is planned to contact potential consumers of such devices to determine the possibilities of practical application of both the devices themselves and the proposed method for synthesizing their parameters.
引言这项工作的目的是在以附加反馈和优化这些反馈的传递函数的形式表示这些装置的基础上,开发一种用于合成铁锹弹性阻尼装置参数的程序,从而可以从具体的实施方法中抽象出来,并对装置参数进行比较评估和合理选择。研究方法。弹性阻尼装置参数的优化是在使用根法研究附加反馈传递函数的特征多项式和设定瞬态过程所需的性质的基础上进行的,瞬态过程是带有给定根的原始运动微分方程的解。结果提出了一种基于附加反馈形式的弹性阻尼装置参数合成程序,以及使用根法优化这些反馈的传递函数,这使人们能够从具体的实现方法中抽象出来,并对装置参数进行比较评估和合理选择。分析结果表明,弹性阻尼装置的参数与瞬态过程的质量之间存在关系,从而可以确定这些参数的有效范围。根据矿用挖掘机掘进机构的实际特点,对其机电系统进行了数值建模,证实了所提出的方法在合成弹性阻尼装置的刚度和阻尼参数方面具有很高的效率。目前,正在创建一个配备弹性阻尼装置原型的实验装置,预计将在该装置上评估所提出的参数合成方法的性能和有效性。在此之后,计划与此类装置的潜在消费者联系,以确定装置本身和拟议的参数合成方法实际应用的可能性。

Introduction. Analysis of existing theoretical and experimental studies has shown that the model approach is the main method of landslide research. The existing mathematical model of landslides does not meet the requirements of the necessary adequacy. Materials and methods. This study uses a mathematical modeling methodology based on catastrophe theory. Results and discussion. To solve this actual problem, in this article authors developed a mathematical model of the landslide process on the concave slopes of mountainous territories. The developed model contains two components. The first of them is a mathematical model of the stress field in the volume of rocks located inside the slope section. This model uses the framework of fractal and multifractal modeling methods developed by the authors. The results of this model research are final expressions for calculating the stress field used rock pressure and bending stress as the external stress field. The superposition of the field induced by these external stresses gives the stress field in the volume of rocks located inside the slope section. Analysis of program implementation of this model showed that there are two areas in the slope section: compressive and tensile stresses adjacent to each other. At the boundary between these areas, there is a discontinuity of the stress field. A displacement surface passes along this boundary, forming a potentially landslide body. Moreover, it was found that a potentially landslide body on a slope is in a state of local and global instabilities. A potentially landslide body tends to occupy the position of the minimum potential energy. Local instability is expressed as the tendency of movement to a stable equilibrium without changing its location in the rock mass. The tendency of landslide body to move down the slope is a demonstration of global instability. The second mathematical model describes the realization of local instability that leads to the formation of a landslide body. Conclusion. According to the model analysis, it was found that the implementation of instability leads to the formation of a landslide body. At the same time, according to this analysis a landslide body can take up three stable equilibrium positions, allowing it to stay on the slope without global instability. Suggestions for practical application and direction of future research. The research results can be used to predict landslides on concave slopes of mountainous territories and to develop new mathematical models allowing to make the analysis of concave slopes of mountainous territories taking into account fracturing.
导言。对现有理论和实验研究的分析表明,模型方法是滑坡研究的主要方法。现有的滑坡数学模型不能满足必要的充分性要求。材料和方法。本研究采用基于灾变理论的数学建模方法。结果与讨论。为了解决这一实际问题,作者在本文中建立了山区凹坡滑坡过程的数学模型。该模型包含两个部分。第一部分是斜坡内部岩石体积应力场的数学模型。该模型采用了作者开发的分形和多分形建模方法框架。该模型的研究成果是计算应力场的最终表达式,使用岩石压力和弯曲应力作为外部应力场。这些外应力场的叠加给出了斜坡断面内岩石体积的应力场。对该模型的程序实施分析表明,在斜坡断面上有两个区域:相邻的压应力和拉应力。在这两个区域的边界处,应力场不连续。位移面沿此边界通过,形成潜在的滑坡体。此外,研究还发现,斜坡上的潜在滑坡体处于局部和整体不稳定状态。潜在滑坡体倾向于占据势能最小的位置。局部不稳定性表现为在不改变其在岩体中的位置的情况下运动到稳定平衡的趋势。滑坡体沿斜坡向下移动的趋势是整体不稳定性的表现。第二个数学模型描述了导致滑坡体形成的局部不稳定性的实现。结论根据模型分析发现,不稳定性的实现会导致滑坡体的形成。同时,根据该分析,滑坡体可以占据三个稳定的平衡位置,使其能够在斜坡上停留,而不会出现整体失稳。实际应用建议和未来研究方向。研究成果可用于预测山区凹坡上的滑坡,并开发新的数学模型,以便在考虑断裂的情况下对山区凹坡进行分析。

Introduction. Western atmospheric jet streams carry moisture over the Northern Tian Shan ridges into the Inner Tian Shan. Long-term weather changes in the Inner Tian Shan diagnose climatic fluctuations in atmospheric moisture transport. This is of considerable interest for understanding the direction of modern climate change in Central Asia. Materials. The area of the At-Bashi Ridge (2700 км2) in Inner Tian Shan, including a large high-altitude Lake Chatyr-Kul (170 km2, 3530 m), were considered. The ridge, with a peak of 4786 m, has a length of 135 km and is characterized by an Alpine type of relief. The initial information related to the period 1982-2022. The list of data used included: FLDASSnowDepth_inst; JRC Monthly Water History, v1.4; ECMWF/ERA5_LAND/MONTHLY (precipitation); NOAA/NCEP_DOE_RE2 (cloud fraction). Also, to diagnose the mountain glaciation state of the At-Bashi Ridge, three satellite images of sub meter resolution dated 09/21/2002, 07/27/2013 and 09/13/2021 were used. The purpose of the work. The aim of the research was to study the humidity regime of the At-Bashi Ridge area during 1982-2022. Research methodology. The change in the average annual snow depth in the test area in the period 1982-2022 was analyzed, as well as the degree of correlation of this parameter with other weather characteristics.Fischer’s criterion acted as a quantitative basis for estimates. Satellite images of sub meter resolution were used to analyze long–term changes in the area of rock outcrops from ice on the slopes of glacial chambers, which diagnoses the glacier state (degradation – stability – growth). Satellite data recorded the process of mountain glaciation growth above the height of 4000 m in the period between 2002–2013. Research results. In order of increasing correlation (F-criterion), with the snowiness of the cold period (October-May) of the At-Bashi Ridge area, the parameters considered were arranged as follows (F=2.11; α=0.01): cloud fraction, F= 3.02; precipitation, F=12.42; the Lake Chatyr-Kul area, F= 12.53; the balance of snow deposits between the windward (north-western) and leeward (south-eastern) At-Bashi Ridge slopes, F= 22.01. According to satellite data, the growth of mountain glaciation in the zone with an altitude above 4000 m in the period 2002-2013 was recorded. Discussion. The At-Bashi Ridge area has three different periods in terms of humidity: dry in 1982-1999 with an average annual snow depth of 0.099± 0.051 m; wet in 2000-2012; 0.192± 0.074 m; and moderately humid in 2013-2022; 0.133± 0.058 m. Ultra-high-resolution satellite images recorded the growth of the mountain glaciation of the At-Bashi Ridge at altitudes of more than 4000 m in the period from 2002 to 2013. This confirms the actual existence of the wet period of 2001-2012. Conclusion. Thus, the current trend of humidity changes of the At-Bashi Ridge does not have an unambiguous direction, but in general, for the period 1982-2022, it is aimed at a certain increase
简介西部大气喷流携带水汽越过北天山山脊进入内天山。内天山的长期天气变化可诊断出大气水汽输送的气候波动。这对于了解中亚地区现代气候变化的方向具有重要意义。材料研究对象为内天山的阿特巴什山脊(2700 км2)地区,包括一个高海拔的大型恰特尔库勒湖(170 平方公里,3530 米)。该山脊最高峰海拔 4786 米,全长 135 公里,具有阿尔卑斯山类型的地貌特征。初始信息涉及 1982-2022 年。使用的数据包括使用的数据清单包括:FLDASSnowDepth_inst;JRC 每月水历史,v1.4;ECMWF/ERA5_LAND/MONTHLY(降水);NOAA/NCEP_DOE_RE2(云量)。此外,为了诊断阿特巴什海脊的山地冰川状态,还使用了三幅亚米级分辨率的卫星图像,日期分别为 2002 年 9 月 21 日、2013 年 7 月 27 日和 2021 年 9 月 13 日。工作目的研究目的是研究 1982-2022 年期间阿特巴什山脊地区的湿度状况。研究方法。分析了 1982-2022 年期间试验区年平均积雪深度的变化,以及该参数与其他天气特征的相关程度。亚米级分辨率的卫星图像被用于分析冰川室斜坡上冰岩石露头面积的长期变化,从而诊断冰川状态(退化-稳定-增长)。卫星数据记录了 2002-2013 年间海拔 4000 米以上山区冰川的增长过程。研究成果。按照与阿特巴什山脊地区寒冷期(10 月至次年 5 月)积雪量的相关性(F 标准)递增顺序,所考虑的参数排列如下(F=2.11;α=0.01):云量,F=3.02;降水量,F=12.42;恰特尔库勒湖地区,F=12.53;阿特巴什山脊迎风坡(西北坡)和背风坡(东南坡)之间的积雪量平衡,F=22.01。卫星数据显示,2002-2013 年期间,海拔 4000 米以上地区的山地冰川面积有所增长。讨论根据超高分辨率卫星图像的记录,2002-2013 年间,海拔 4000 米以上的阿特巴什山脊地区山地冰川发育。这证实了 2001-2012 年湿润期的实际存在。结论因此,阿特巴什山脊目前的湿度变化趋势并没有明确的方向,但总的来说,在 1982-2022 年期间,其目标是在一定程度上增加山区和恰特尔库勒湖地区的积雪量。显然,在当前气候变化的同时,西部大气喷流将水汽从天山北部前缘山脉转移到内天山和中天山山脊的能力也在增强,甚至可能在某些时期伴随着这些地区山地冰川的增加。

According to satellite data, the growth of mountain glaciation in the zone with an altitude above 4000 m in the period 2002-2013 was recorded. Discussion. The At-Bashi Ridge area has three different periods in terms of humidity: dry in 1982-1999 with an average annual snow depth of 0.099± 0.051 m; wet in 2000-2012; 0.192± 0.074 m; and moderately humid in 2013-2022; 0.133± 0.058 m. Ultra-high-resolution satellite images recorded the growth of the mountain glaciation of the At-Bashi Ridge at altitudes of more than 4000 m in the period from 2002 to 2013. This confirms the actual existence of the wet period of 2001-2012. Conclusion. Thus, the current trend of humidity changes of the At-Bashi Ridge does not have an unambiguous direction, but in general, for the period 1982-2022, it is aimed at a certain increase","PeriodicalId":37608,"journal":{"name":"Sustainable Development of Mountain Territories","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139333642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology for the environmental assessment of the state and sustainability of agrolandscapes at the local level makes it possible to determine their agroindustrial potential and prevent the degradation of agricultural land. On the example of a municipal district with an area of 198 thousand hectares, located in the dry steppe zone of the Altai Krai, an environmental assessment of the state and sustainability of agricultural landscapes was carried out. We compiled a unique landscape map-scheme on which five landscape areas were identified. It was established that 80% of the territory is occupied by ancient alluvial flat and slightly undulating plains with chestnut soils, in combination with dark chestnut and meadow chestnut soils, solonetsous in places. Agricultural landscapes are everywhere subject to deflationary processes. It was determined that the agricultural development of the territory exceeds 94%, the coefficient of ecological stability of the agricultural landscape is 0,27, the coefficient of anthropogenic load is 3,62 points, the coefficient of the ecological state of the agricultural landscape is 0,30, which characterizes the territory as extremely highly developed (59% of landscapes – very unstable, 36% – unstable, and only 3 % and 2 % – very and moderately resistant, respectively). The results of the research can be used in the design and organization of farming systems at the level of an agricultural organization. Conclusions. 1. It has been established that the studied agrolandscapes are typical for large areas of the south of Western Siberia and Northern Kazakhstan in terms of a whole range of conditions and factors. 2. Particular attention in the environmental assessment of the state and sustainability of agricultural landscapes at the local level should be given to the structure of the land fund, agricultural land, sown areas and crop rotations. 3. It was determined that the studied agrolandscapes are experiencing a critical anthropogenic load, degradation (deflationary) processes are manifested everywhere on the territory, sustainability indicators characterize two-thirds of the territory as very unstable, more than 30% as unstable, and only 5% of landscapes are stable. 4. Research results can be used in the design and organization of farming systems at the level of an agricultural organization.

Introduction. Despite a fairly wide range of methods currently used for the chemical and elemental analysis of rocks and archaeological artifacts, many questions regarding the qualitative and quantitative accuracy of the analysis and the distribution of elements over the surface and volume of the sample with a high degree of locality remain open. In this regard, to solve these issues, in this work, for the first time, the method of X-ray photoelectron spectroscopy (XPS) was proposed and tested, which allows unambiguous and high-precision chemical identification of an object and the construction of its elemental map of the surface and volume. Materials and methods. The physical principles of the XPS method operation, which determine its record high qualitative and quantitative accuracy, are considered, a description of one of the most highly efficient X-ray photoelectron spectrometers Escalab 250 Xi, features of its operation and methods of adaptation for the study of rocks and archaeological artifacts are given. A special methodological advantage is the possibility of sample preparation and research under ultrapure conditions of ultrahigh vacuum. Results. XPS spectra were obtained in a wide range of photoelectron binding energies, which makes it possible to cover a fairly wide range of chemical elements that make up rocks and archaeological artifacts. With a high degree of spatial locality – at the level of 30 μm – elemental maps of the objects under study were built. Using the additional advantage of the method, based on the analysis of the energy position and the shape of the photoelectron spectral line, the chemical states of the elements that make up the samples were determined. Discussion. The obtained results of high-precision chemical analysis, combining both the general composition of the elements of the test sample as a whole and their spatial distribution with a high degree of locality, make it possible to achieve greater unambiguity in the identification of the objects under study compared to currently used analysis methods. Such high accuracy makes it possible to establish a correspondence between the composition of the rock and the archaeological artifact from the same area. The non-destructive nature of the XPS method, combined with ultrapure analysis conditions, makes it possible to ensure the safety of often unique objects. Conclusion. As a result of the study, it was shown that the XPS method can be quite effectively used for high-precision qualitative and quantitative analysis of rocks and archaeological artifacts, which is achieved both by the features of the method itself and by sample preparation and study of materials in ultrapure conditions of ultrahigh vacuum. The advantage of the method is the combination of a number of possibilities, such as not only the elemental, but also the chemical composition of objects, as well as the possibility of chemical mapping of the surface and analysis of the depth of the object with high
导言。尽管目前用于岩石和考古文物化学和元素分析的方法相当广泛,但有关分析的定性和定量准确性以及元素在样品表面和体积上的分布和高度定位的许多问题仍然悬而未决。为此,为了解决这些问题,在这项工作中,首次提出并测试了 X 射线光电子能谱(XPS)方法,该方法可以对物体进行明确和高精度的化学鉴定,并构建其表面和体积的元素图谱。材料和方法。考虑了 XPS 方法运行的物理原理,这些原理决定了该方法在定性和定量方面的高准确性,并介绍了最高效的 X 射线光电子能谱仪之一 Escalab 250 Xi、其运行特点以及适用于岩石和考古文物研究的方法。该方法的一个特殊优势是可以在超高真空的超纯条件下进行样品制备和研究。结果。XPS 光谱是在很宽的光电子结合能范围内获得的,因此可以涵盖构成岩石和考古文物的相当广泛的化学元素。通过高度的空间定位(30 微米级),绘制了研究对象的元素图。根据对光电子光谱线的能量位置和形状的分析,利用该方法的额外优势,确定了构成样品的元素的化学状态。讨论高精度化学分析所获得的结果,结合了测试样品整体元素的一般组成及其空间分布的高定位性,与目前使用的分析方法相比,在鉴定所研究的对象时能达到更高的明确性。如此高的精确度使得岩石成分与同一地区的考古文物之间建立对应关系成为可能。XPS 方法的非破坏性与超纯分析条件相结合,可以确保往往独一无二的文物的安全。结论。研究结果表明,XPS 方法可以非常有效地用于岩石和考古文物的高精度定性和定量分析,这既得益于该方法本身的特点,也得益于在超高真空的超纯条件下进行的样品制备和材料研究。该方法的优势在于将多种可能性结合在一起,例如不仅可以分析物体的元素,还可以分析其化学成分,还可以绘制物体表面的化学图谱,并以高空间分辨率分析物体的深度。研究成果可用于解决从考古到山区开发等一系列问题,特别是通过开发科学储备来建立有效的地球化学屏障,从而解决环境问题。进一步的研究应集中在开发技术上,使 XPS 方法适用于获得所研究对象的三维断层模型,这将提高其识别质量,特别是从地质学和考古学的角度来看。

Introduction. In order to develop promising deposits of non-ferrous metals in the Arctic zone, in particular the Pavlovskoye lead-zinc deposit on Novaya Zemlya, it is necessary to develop climate-saving geo-technologies for mining. In this connection, a concept of conservation geo-technology has been developed and proposed through the use of a specially designed floating complex of mining equipment, included together with the quarry equipment in a single technological chain for the extraction of ore raw materials and its processing into concentrate. However, for the full functioning of the concept of this geo-technology, it is necessary to carry out preventive maintenance and repair of mining equipment at the site of its operation on a floating complex. Research methods and materials. The methodological basis of the work is a systematic approach to the studied means of carrying out repair and restoration works of mining machinery and equipment, which includes both theoretical analysis and generalization of the results of fundamental and applied works of domestic and foreign authors, including methods and theories of designing technology for repairing metalworking and mining processing complexes, multicriteria analysis and simulation modeling. Research results. The article proposes a new technology for the implementation of repair work to restore the working surfaces of hollow loading and unloading support trunnions of hydrostatic sliding bearing units of a drum mill in cramped deck conditions of a floating complex of mining equipment for the development of deposits in the Arctic zone. The structure of the built-in mechanized modular machine tool complex is developed and presented, with the help of which the hollow support trunnions of the drum mill are directly machined according to the patented repair technology. Conclusion. It is shown that the use of the described repair technology by means of an embedded mechanized modular complex will reduce the complexity of the overhaul of the trunnions without the need to perform dismantling work to disconnect the mill drum body from the hollow trunnion caps, which has a positive effect on the accuracy of processing the working surfaces of hollow trunnions.
导言。为了开发北极地区前景广阔的有色金属矿藏,特别是新泽姆利亚的巴甫洛夫斯科耶铅锌矿藏,有必要开发节约气候的采矿地质技术。为此,开发并提出了节约型地质技术的概念,即使用专门设计的浮动采矿设备综合体,与采石设备一起组成单一的技术链,用于提取矿石原料并将其加工成精矿。然而,为了使这一地质技术概念充分发挥作用,有必要在浮动综合体上的采矿设备运行现场对其进行预防性维护和修理。研究方法和材料。这项工作的方法论基础是对所研究的采矿机械设备维修和修复工程的手段进行系统的研究,其中包括理论分析和对国内外作者的基础性和应用性著作成果的归纳,包括金属加工和采矿加工综合体维修技术设计的方法和理论、多标准分析和模拟建模。研究成果。文章提出了一种新技术,用于在北极地区矿藏开发浮动采矿设备综合体狭窄的甲板条件下实施维修工作,以恢复滚筒磨机静压滑动轴承单元空心装卸支撑耳轴的工作面。开发并展示了内置机械化模块化机床综合体的结构,在该结构的帮助下,可以根据专利修复技术直接加工滚筒磨机的空心支撑耳轴。结论研究表明,通过嵌入式机械化模块组合机床使用所述维修技术将降低耳轴检修的复杂性,而无需进行拆卸工作,将磨机滚筒体从中空耳轴盖上拆卸下来,这对中空耳轴工作面的加工精度具有积极影响。

Introduction. By Decree of the Government of Russia dated September 25, 2019 No. 1248, a decision was made to create an all-season tourist and recreational complex “Mamison” on the territory of the Alagirsky district of the Republic of North Ossetia – Alania, in the upper reaches of the Ardon River, the valleys of the Mamikh-Don and Zemegon-Don rivers. One of the most favorable areas is the high-mountain gorge Mamison, where the Zemegon-Don and Kozydon-Don rivers merge, which, downstream, form the Mamikh-Don river. To date, the territory of the Mamison ATRC has been poorly studied in meteorological and hydrological terms. There are practically no studies of the physical properties of snow; the peculiarities of changes in the weight of the snow cover depending on the absolute height have not been identified, as, for example, at the Elbrus ATRC in Kabardino-Balkaria. The work is devoted to the analysis of the dynamics of the average seasonal values of outdoor air temperature, snow cover depth and the amount of precipitation during the cold period (October – May) from 1981 to 2022. On the territory of the Mamison All-Season Tourist and Recreational Complex. Research methods and materials. The work carried out a mathematical and statistical analysis of the meteorological parameters on which the snow avalanche regime depends to the greatest extent. To analyze the average seasonal values of snow depth, air temperatures and total (for the season) amount of precipitation, the work used weather data for the cold period (October – May) obtained at the snow avalanche station (SLS) Roki Pass (from 1981 to 2022). Research results. Mathematical analysis showed that the mid-season snow depth changes linearly, the trend is negative. Mid-season air temperature changes linearly, the trend is also positive. The trend in changes in the seasonal total values of the amount of solid precipitation is positive, the highest amount of precipitation occurs in the spring months – March, April, May (3396 mm, 4809 mm, 4910 mm, respectively). Discussion of research results. The observed changes were manifested in a decrease in the depth of snow cover, a change in precipitation patterns, and an increase in the average seasonal characteristics of the temperature regime. In view of these changes, we can say that the decrease in avalanche activity in the Roki Pass area is associated with interannual changes in the depth of snow cover, which is the main factor in avalanche formation. Conclusions. It was found that from 1981 to 2022, the average annual snow depth decreased by 0.56 cm per year. An expression for the time variation of snow cover height is obtained. Suggestions for practical applications and future research directions. The results obtained have practical significance in the development of mountainous territories and should be taken into account when designing infrastructure facilities of the Mamison ATRC.
导言。根据2019年9月25日第1248号俄罗斯政府令,决定在北奥塞梯共和国阿拉吉尔斯基区--阿拉尼亚境内的阿尔东河上游、马米赫-顿河和泽梅贡-顿河河谷建立 "马米松 "四季旅游休闲综合体。最有利的地区之一是马米松高山峡谷,泽梅贡-顿河和科兹顿-顿河在此汇合,下游形成马米克-顿河。迄今为止,在气象和水文方面,对马米松地区研究中心的研究很少。几乎没有对雪的物理特性进行过研究;也没有发现雪层重量随绝对高度变化的特殊性,例如在卡巴尔达-巴尔卡尔地区的厄尔布鲁士地区研究中心。这项工作致力于分析 1981 年至 2022 年寒冷时期(10 月至 5 月)室外气温、积雪深度和降水量的季节平均值的动态变化。研究地点位于马米松四季旅游休闲综合体境内。研究方法和材料。这项工作对雪崩机制在最大程度上所依赖的气象参数进行了数学和统计分析。为了分析雪深、气温和降水总量(季节性)的季节平均值,该研究使用了从罗基山口雪崩站(SLS)获得的寒冷时期(10 月至 5 月)的气象数据(1981 年至 2022 年)。研究结果。数学分析显示,季节中期雪深呈线性变化,趋势为负。季节中期气温呈线性变化,趋势也是正的。固体降水量的季节总值变化趋势为正,降水量最大的月份出现在春季--3 月、4 月、5 月(分别为 3396 毫米、4809 毫米、4910 毫米)。研究结果讨论。观测到的变化表现为积雪深度的减少、降水模式的改变以及气温制度平均季节特征的增加。鉴于这些变化,我们可以说,罗基山口地区雪崩活动的减少与积雪深度的年际变化有关,而积雪深度是雪崩形成的主要因素。结论研究发现,从 1981 年到 2022 年,年平均积雪深度每年减少 0.56 厘米。得出了雪盖高度的时间变化表达式。对实际应用和未来研究方向的建议。所获得的结果对山区的发展具有实际意义,在设计马米松藏羚羊保护区的基础设施时应加以考虑。

Introduction. Among the current global trends, it is worth highlighting the problem of ensuring environmental safety as a priority for the sustainable development of countries and regions. The most rational way to solve this problem is to follow the concept of «Green Growth», the main principle of which is to conserve natural resource potential by moving away from the practice of imposing sanctions and environmental restrictions in favor of creating low-waste and waste-free production, emissions from which are used several times or are subject to complete disposal. Using the example of the development of innovative technologies in polymer chemistry of the Kabardino-Balkarian Republic, the article substantiates the relevance of creating and promoting regional eco–oriented innovative startups, effective not only from the point of view of ensuring environmental safety of the population of the regions of the country, but also in the socio-economic aspect, since waste-free innovative technologies Environmental safety is one of the most pressing problems of the modern period of social development and it is associated mainly with the growth of the world’s population, the increase in production capacity and the social processes of people’s lives. Ensuring environmental safety is one of the criteria for the sustainability of regional development, which, in addition to socio-economic well-being and improving the quality of life of people, includes environmental well-being and the integrity of the natural environment. Based on this, it can be stated that in the process of ensuring the environmental safety of regions, it is necessary to take into account all issues of interaction between people and the natural environment (environmental protection, flora, fauna, ensuring high quality food, clean air, water surfaces, etc.) in order to achieve not only the environmental well-being of the population, but also the integrity of the natural environment, regardless of the well-being of people. The purpose of the study is to substantiate the rationality of following the “green” socio-economic concept of regional development through the modernization of production facilities, the use of eco-innovations, the development and promotion of fully or partially regenerated environmentally-oriented start-ups, both from the point of view of increasing the socio-economic criteria of regional development and from the side of ensuring environmental safety. Research objectives that allowed us to achieve our goal: - assessment of the regulatory and legislative “agenda” and guidelines for the country’s development in the field of ensuring socio-ecological and economic sustainability; - analysis of global and Russian trends in the development of polymer chemistry; - study of the economic efficiency and environmental feasibility of creating and implementing environmentallyoriented startups using the example of the CBD polymer chemistry industry.
