| Popis: | The authors of the paper consider the concept of further prospective development of mining enterprises. The basis of this concept are scientific results obtained during the study of physical and chemical processes of solids conversion into the gaseous state: coal → gaseous fuels. It was established that the main base of development of mining regions is a mining power-chemical complex. The basic segment of which is a well underground coal gasification station. It is established that increase of indicators of efficient operation of the station from gasification is possible by synthesis of technical and technological decisions on the use of coal seam energy. When coal gasification is over, the gasifier passes into a mode of thermal generator with the use of alothermal technique to remove heat and thermic decomposition products from the degassed space of the gasifier. Generator gas at its initial temperature (1100 – 1300oС) around an underground gasifier creates a powerful heat boiler with a temperature regime of 200 – 300oС. It was established that at work of six gasifiers on a coal seam with thickness of 1.0 m with geometrical parameters each at a width of 30 m and at the length of 450 m energy-thermal power will be 237.8 MW. At the same time, additional energy resources can be obtained by involving segments of alternative forms of energy supply to the life cycle of the mining enterprise. |
