Omelchenko T. Economic and mathematical modeling of gas products utilization within the coal production process

The dissertation deals with a new solution and theoretical feasibility of scientific problem to develop scientific and methodological bases, conceptual approaches and tools of analysis, mathematical modeling and investment management of coal mines. In the work was analyzed and expanded the system of factors affecting the production, economic and financial processes of coal mining enterprises, defined dependencies between them, the volume of extracting and using coal-bed methane, investments in utilization system. The tendency of modern power system depends on the problem of environmental pollution: reduction of greenhouse gases, leading to an increase in temperature, and the search for alternative ecologically pure and cost-effective energy sources. Dynamic economic developing of the world market last year directly affected the increase in supply of energy and stimulated demand. Reducing energy reserves affect the growth of their value. There is no reason to focus on nuclear power until solved the issues related to safety of nuclear power stations and creating long-term storage facilities of nuclear waste. Buying nuclear fuel and equipment to nuclear power plants, the state, as in the case of oil and natural gas, supports the third-party economy. There are actual risks that arise, because of the low mobility of nuclear turbines. At the same time at the national level concerns the problem to increase the coal consumption by domestic thermal power stations and reduce the anthropogenic load on the environment. Heat energy has traditionally been the largest share of ecologically dangerous with hydrocarbon emissions, and Ukrainian fuel and energy stations will continue to generate environmental risks (including their technical condition and the chronic lack of investment resources to technical modernization). For this purpose were justified necessary investments for purchasing and renovation of fixed assets of the coal industry (cogeneration system) for the removal and utilization of coal-bed methane in four directions. The system of economic and mathematical models was built, which allows to obtain important information for making decisions to invest in coal mining company, determine the amount of investment from own funds and determine the amount of company profits in the case of realization the investment project for methane industry developing. There was implemented decision of an actual problem to distribute the recovered coal mine gas methane as alternative energy source for maximizing the process of economic benefit from investing into modernization of degassing and utilization systems. Designed on the basis of economic and mathematical models algorithm of forecasting allows analyze complex of internal and external factors affecting the economic development of the company and reasonably make management decisions for enterprise development and flexible reaction on customer's demand.
