System of headings in the hard coal deep mine and method of exploitation in the hard coal deep mine for mining of coal seams deposited at the depth below the lowest mining floor

摘要

the invention relates to the workings in the deep-sea coal and operation in the deep-sea coal for selecting decks aged at large depths below the lowest level of extractive industries, particularly for the mines with comprehensive balance sheet of coal beds.system has a battery (8) for mining underground coal gasification podpoziomowego deck (6), which has at least two and three basic workings favourably (8a, 8b, 8c).with the basic workings of stress (8a, 8c) are made krzywoliniowe injection openings (9a, 9c) to the carbon (6) and the basic workings of central (8b) are made corresponding made out wells (9b), which together form the skeletons georeaktoru00f3w (10).way is first to lowest level (4) carried out excavation mining battery (8), after which georeaktoru00f3w skeletons (10) odmetanowuje, and subsequently initiates in gasification processes. by the injection openings (9a, 9c) is zgazowuju0105ce media and by wells (9b) from gasification products and pipeline (14) is discharged to the surface.after the completion of the work georeaktoru00f3w (10) first wychu0142adza them inert gas, after which the resulting kawerny fills with good dust elektrownianymi.
