One of the difficult issues in underground mining is the ground control of roadway subject to mining induced stresses. As a longwall face advances, the state of initial stresses dramatically changes. Accordingly, lateral abutment pressure forms on the pillar and frontal abutment pressure on the roof and lateral sides of the roadway. These pressures will lead to severe deformation and deterioration of the rock mass surrounding the entries. In this paper, a systemic study on this issue is proposed using the combination of numerical modeling and in-situ monitoring which was carried out at a coal mine in the Lu.An Group, China. The condition of stress redistribution caused by mining-induced stresses and the state of the surrounding rock mass of the roadway situated in front the work face are systematically investigated. Different patterns of support and reinforcement as well as their effects on the stability of the roadway are also presented.

Будущее любой нации определяется, прежде всего, здоровьем подростков, их репродуктивными способностями. Состояние репродуктивного здоровья подростков в настоящее время является предметом обсуждения не только среди специалистов, но и в обществе. Это говорит об особой остроте и актуальности проблемы. Пубертатный период, как период формирования полового созревания организма, занимает важное место в формировании женской репродуктивной системы, функционирование которой во многом зависит от совместимости и развития девочки в период полового созревания. Особенности пубертатного периода влияют на состояние репродуктивного здоровья женщины в течение всей ее жизни, ее фертильность, а также на демографическую ситуацию в стране [1,2]. Статистические данные за последнее десятилетие показывают, что наряду с ярко выраженными неблагоприятными тенденциями в здоровье всего населения наблюдаются значительные изменения среди девочек-подростков. По мнению исследователей, устойчивость негативной динамики среди подростков сохраняется, так как во многом это связано с неблагоприятными экологическими условиями, несбалансированными физическими нагрузками, различными факторами, такими как хронический стресс и неграмотность населения в отношении собственного здоровья. Кроме того, большое значение имеет и экономическая ситуация. В связи с этим проведенный литературный обзор направлен на углубленное изучение проблемы. The future of any nation is determined, first of all, by the health of adolescents, their reproductive abilities. The state of adolescent reproductive health is currently the subject of discussion not only among specialists, but also in society. This indicates the special acuteness and urgency of the problem. Puberty, as the period of formation of puberty of the body, occupies an important place in the formation of the female reproductive system, the functioning of which largely depends on the compatibility and development of the girl during puberty. The peculiarities of the puberty period affect the state of a woman's reproductive health throughout her life, her fertility, as well as the demographic situation in the country [1,2]. Statistics over the past decade show that, along with pronounced adverse trends in the health of the entire population, there are significant changes among adolescent girls. According to the researchers, the stability of the negative dynamics among adolescents remains, as this is largely due to unfavorable environmental conditions, unbalanced physical activity, various factors such as chronic stress and illiteracy of the population in relation to their own health. In addition, the economic situation is also of great importance. In this regard, the literature review is aimed at an in-depth study of the problem.

Background. Preserving the health of the population, including those involved in sports, is one of the priority directions of the state policy of the Russian Federation. In accordance with the existing legislative and regulatory framework, a system for monitoring the quality and safety of medical care is being implemented in health care institutions, which also applies to medical and physical training services. One of the levels of functioning of such a system is the activity of the medical commission. Intensive training and competitive loads make increased demands on the body and are considered a risk factor for the health of athletes, which serves as the basis for their in-depth medical examination and dispensary observation. Therefore, the primary task of the medical commission during the prophylactic medical examination of athletes is to issue an expert opinion in difficult cases regarding the training and competitive activity of persons with deviations in the state of health.The objective of the research was to study of the activities of the medical commission during the prophylactic medical examination of athletes in the conditions of a medical and physical service on the basis of a scientific analysis of the results of its work for two years.Materials and methods. We studied the medical documentation of athletes who passed the medical commission for two years (2018–2019; n = 82 and n = 81, respectively). The nature of the decisions made and the structure of their reasons were analyzed using the Pearson chi-square test with amendments.Results. The share of positive and negative decisions of the commission, as well as temporary suspension from sports by years, their statistical dependences and the strength of the connection between the results are shown. The stability of the negative conclusions of the commission, as well as the structure of their reasons, was revealed (р ˃ 0.05). At the same time, in the second year of observation, they were more often temporarily suspended from sports due to musculoskeletal system diseases and less often as a result of injuries (p < 0.05).Conclusion. The main regularities of the distribution and formation of expert decisions of the medical commission for the years under study were revealed. The necessity of its activity for the medical and physical training service during the medical examination of athletes is noted, as well as the factors that prevent this are indicated.

One of the main criteria for economic development is the size of the public debt and its dynamics. The article considers the impact of public debt on the financial security of Ukraine. The views of scientists on the essence of public debt and financial security of the state are substantiated. An analysis of the dynamics and structure of public debt of Ukraine for 2014-2019. It is proved that one of the main criteria for economic development is the size of public debt and its dynamics. State budget deficit, attracting and using loans to cover it have led to the formation and significant growth of public debt in Ukraine. The volume of public debt indicates an increase in the debt security of the state, which is a component of financial security. Therefore, the issue of the impact of public debt on the financial security of Ukraine is becoming increasingly relevant. The constant growth and large amounts of debt make it necessary to study it, which will have a positive impact on economic processes that will ensure the stability of the financial system and enhance its security.

The silvicultural principles of a forest management plan for Canton Neuchâtel reveals itself as steeped in a systemic approach that allows us to consider the forest as a truly living system. In this context, it seems judicious to the author to conceive of the body forest personnel as a group of responsible people who share certain common ethics and who, in their work, promote the emergence of collective services recognised as beneficial to the state and which would be supported by public funding for the good of the entire community.

Purpose. Increasing the uniformity of distribution of mineral fertilizers and other bulk materials due to the stability of their feed from the body to the spreading working bodies using the top feeder. Methods. The following methods are used to achieve this aim: the method of comparing the differences between individual groups of fertilizers, the method of analyzing the properties of a new technical system, the method of functional inventiveness, and the methods of theoretical and analytical mechanics. Results. The traction body of the conveyor of the upper feed of the body fat body machine for mineral fertilizers and other bulk materials was substantiated and the relationship between the height of its scrapers and the distance between them was established, as well as the nature of the mineral fertilizer pressure on the curvilinear wall of the body. In addition, the design of the advanced body fertilizer spreader is justified, which ensures a stable flow of fertilizers from the body due to the improvement of the top feeder. Conclusions. Because of the conducted researches, the advantages of machines equipped with top feeder are found. They create the conditions for the forced feeding mineral fertilizers and other loose materials from the container to the distribution bodies, which is a prerequisite for their evenness on the surface. With this, the imperfection of known machines with the top feeder constrains their introduction into agricultural production. On this account, a more thoroughly constructed solution of the body feeder of the top feed is substantiated, in which the conveyor provides a stable supply of fertilizers from the body with reduced energy consumption during operation. Keywords: analysis, feed, upper device, conveyor, stability, fertilizers, flow ability, body.
