Energy stability in the context of modernization of post-soviet countries

To use the latest technologies for processing man-made deposits in difficult conditions, in particular with limited reserves and capacity, the theory of developing investment decisions should be able to reflect the relationship between different levels and subsystems of industry subordination, as well as taking into account market conditions, which dictates the level of demand and prices. It is possible to take into account these relations in investment projects by a combination of logical and mathematical methods. The systematic approach and all the methods of decision theory are valuable precisely because, based on a comparison of cost-effectiveness and results of these costs, as well as on the basis of decisionmaking methods, they make it possible to justify new optimal solutions in investment projects for the development of coal-mining regions. Diversification of production as a form of organization of productive forces has attracted the attention, first of all, of coal production managers and environmentalists in connection with the demonopolization of the economy, the conversion of the militaryindustrial complex, and the expansion of competition. However, the economic science has not sufficiently studied the economic, technological and social aspects of the phenomenon. The theory could not foresee the emergence of many problems faced by enterprises of post-Soviet countries, having received the freedom to choose any type of activity that is not prohibited by law. This is especially true for mining enterprises. Therefore, any suggestions on the diversification of production in regions where inefficient coal mines remained and the transcendental ecological situation has formed can be considered a certain contribution to solving the problem of economical use of natural resources. Being a tool to eliminate imbalances in reproduction and redistribution of resources, the diversification of production and business activities has different goals and determines the direction of economic restructuring. Since neither domestic economic theory, nor empirical research provides us with sufficient information for analysis as the following statements are based on world experience known in Ukraine.
