The national strategy for the development of artificial intelligence for the period up to 2030 sets the task of a significant increase in the number of scientific articles by Russian scientists in this field. To do this, it is necessary to navigate the priorities, problems and prospects of scientific research carried out all over the world. However, there is currently not a single generalizing work on regional economic studies using artificial intelligence algorithms. Therefore, the object of the study was the world array of scientific publications on regional economic research, and the subject of the study was a lot of articles on the use of artificial intelligence algorithms in such studies. The purpose of the work was to generalize world experience. To select the necessary publications, a self-organizing semantic search algorithm has been developed, based on the ideas of content analysis, expert systems and machine learning. The search was carried out in the Scopus database. About a hundred articles were identified. A brief description of ten artificial intelligence algorithms used in regional economic research is given. Analysis of world experience has revealed five features: algorithms are not used to solve all research problems; are not aimed at creating a universal autonomous artificial intelligence system; are increasingly focusing outside of artificial neural networks; rarely used in combination; in domestic works are less diverse than in competing countries. It is proposed to focus efforts on identification of economic regions of specific functioning of production, transport and service systems of artificial intelligence; identification of territorial digital platforms; analysis of the intensity of gravitational interaction of geographically distributed socio-economic objects through 5G and 6G telecommunication networks; assessment of the direction and volume of regional information flows; determination of models of spatial diffusion of innovations in artificial intelligence among Russian regions. The accelerated development of these areas with significant government support will allow Russia to provide a methodological gap from other countries in the field of regional economic research by 2030

In recent years, living conditions of a population have changed rapidly due to complex social, economic, cultural, political and other processes. This naturally leads not only to a transformation of the system of values, motivation, worldview, but also an entire way of life. High rates of these changes simultaneously led a delegation given, on the one hand, a diversity of forms of response behavior, from the other – their gradual integration into the socio-economic relations in a search result models of individual and collective adaptation to a new dynamic environment, characterized by high uncertainty and heterogeneity. Thus, the purpose of this study is to identify and describe the main models of population adaptation on an interdisciplinary basis, not limited to an analysis of complex processes within a single field of knowledge. In this regard, the task is to find a way to harmonize (coordinate) different points of view on a nature of a single phenomenon. The object of our research is a variety of adaptation processes of a population to dynamically changing conditions of its life. At the same time, the subject should be a wide range of different types of interactions between a population and an external environment, as well as a population “within itself”, as part of the model of its adaptation to changing conditions. To achieve the goal and solve problems, a set of methods that complement each other is used, namely: theoretical analysis and synthesis, systematization and comparative analysis. As a result, it was found that population adaptation is a rather complex phenomenon, the study of which goes far beyond the formal framework of any one field of knowledge, being at their intersection, which requires the search for new approaches that allow integrating explanations of the nature of phenomena that are currently interpreted within their paradigms. The article presents the main types of models of population adaptation to dynamically changing socio-economic conditions of life, their features, identity and differences, as well as areas of application

PAO “Priargunsky Production Mining and Chemical Association” has been working on reserves of uranium deposits of the Streltsovsky ore field for more than 50 years. During this period, most of the rich ores have been worked out by traditional mining and physical technology. The share of poor and ordinary ores remains significant, but traditional technology does not provide the necessary level of profitability. Therefore, the widespread introduction of physicochemical technology: underground block (BPV) and heap leaching (KV) can be a decisive moment in the continuation of the operation of these deposits. The applied technology of underground block leaching has one significant drawback – a low rate of uranium recovery into a productive solution, which significantly reduces the effectiveness of this technology in the development of poor uranium deposits. To increase the yield of uranium into the productive solution, it is necessary to analyze the entire preparation and leaching process and establish the main reasons for the low rates of transition of uranium to a mobile state. For this purpose, it is proposed to simulate the underground leaching process by building visual models of halos spreading of solutions along shrinked ore mining mass accumulated in an underground chamber. During the simulation, it was found that the distribution of the size classes of the broken ore pieces in the chamber can be predicted at the stage of drilling and blasting operations, and when determining the line of least resistance W and the distance between the ends of the wells, take into account the diameter of the controlled crushing zone R_p. At the same time, 3 zones of granulometric compositions are formed: a re-grinding zone, an optimum zone and a non-carbarite exit zone. The flow of solutions through these zones will differ the more significantly, the higher the height of the chamber. In a zone with larger crushing, an almost steep distribution of the solution spreading front is expected. Accordingly, the smaller the fraction, the lower the front to the horizontal is. The following functions are offered to simulate filtering processes: – it is possible to control the flow of working solutions to the fan of irrigation wells in order to achieve optimal leaching parameters, i.e. to quickly control the process; – knowledge of the law of distribution of irrigation flares makes it possible to select the optimal grid of location of single sprinklers
PAO“Priargunsky Production Mining and Chemical Association”从事Streltsovsky矿田铀矿储量勘探工作已有50多年。在此期间，大部分富矿都是通过传统采矿和物理技术开采出来的。劣质和普通矿石的份额仍然很大，但传统技术不能提供必要的盈利水平。因此，广泛采用物理化学技术:地下区块(BPV)和堆浸(KV)可以成为这些矿床继续开采的决定性时刻。地下区块浸出的应用技术有一个明显的缺点，即铀回收到生产溶液中的比率低，这大大降低了该技术在开发贫铀矿床方面的有效性。为了提高生产液中铀的产量，有必要对整个制备和浸出过程进行分析，并确定铀向流动态过渡率低的主要原因。为此，提出通过建立矿体在地下硐室内堆积的收缩矿体中溶液晕扩散的可视化模型来模拟地下浸出过程。在模拟过程中发现，在钻爆阶段，可以预测破碎矿块在硐室内的粒度分布，在确定最小阻力线W和井端间距时，考虑控制破碎区直径R_p。同时，形成了3个粒度组成区:再磨区、最佳区和非碳化石出口区。通过这些区域的溶液流动差异越大，腔室的高度越高。在破碎程度较大的区域，预计溶液扩散锋的分布几乎是陡峭的。相应地，分数越小，锋面到水平面的距离就越低。提供以下功能来模拟过滤过程:-可以控制工作溶液流向灌溉井的风扇，以达到最佳的浸出参数，即快速控制过程;-了解喷灌火炬的分布规律，可以选择最佳的单喷头位置网格
