“…The quantitative estimate of the influence exerted by the coal seam structure on the coal strength characteristics is also required as the latter govern, alongside with the other factors, the dynamic load of the mining machine motor [7,8,11,[16][17][18].…”

“…The load spectrum governs the limit torque of transmission mechanism, allowable torsion torque with regard to durability of transmission gears etc., i.e., the determinants of the above-listed constraints. First of all, it is necessary to determine structure and properties of coal seams, estimable using an aggregate index of equivalent coal cuttability A eqv [8,9], and to find v mechanisms of their effect on pick failure.…”

The article is devoted to the problem of reliable and stable functioning of the Russian electric power complex. The analysis of structural transformations in the electric power industry and statistical data allowed the authors of the study to conclude that in the industry there is a decrease in the reliability of energy facilities, the stability of the energy system is being violated, and the level of physical and moral depreciation of fixed assets is increasing. It was established in the work that in order to maintain the balance of production and consumption of electric energy, to ensure the necessary level of development of the electric power complex and economic stability, it is necessary to integrate energy enterprises into a single structural mechanism, which can be represented as a holding company. At the end of the work, a mechanism of convergence and ensuring the sustainability of the electric power complex is presented, containing measures for the integration of energy enterprises, the development of a program for ensuring stability and monitoring the technical condition of the energy system. In conclusion, the study presents the main findings and results of the work.

The article is devoted to the conditions and principles of the functioning of the generating complex in a changing external and internal environment. The study determined that the stability of the system is the most important state within which it is possible to streamline the production process. At the same time, in order to ensure stability, it is necessary to determine and manage the factors affecting the state of the system. In the generating complex of the electric power industry, these factors should be divided into the mega-, macro-, meso- and microenvironment, the characteristics of which are presented in the study. The paper presents a scheme that includes the main factors affecting the sustainable development of the generating complex of the electric power industry. The study defines the conditions for regulation and management of factors that ensure the stability of the generating complex. In conclusion, the study presents the main findings and results of the work.
