发明名称 PROCESS FOR TREATING CARBON CHANNELS BEFORE THE UNDERGROUND GASIFICATION OF COAL
摘要 <p>A method of processing recently bored channels when putting into operation an underground gas generator (underground gasifier), consisting, on the one hand, in forced air blowing and, on the other hand, in taking away hot gases, is characterized by determining the magnitude of the hydrostatic pressure by measuring the hydrostatic column of underground waters in a vertical direction from the point at which air is forced into the well to the level of the underground waters, and adjusting the outlet section of the gas discharging wells. This permits maintaining in the boring channel a pressure at a level which is not less than that produced by the hydrostatic column to preclude an inflow of underground waters to the channel being processed. The temperature in the channel is raised at a rate from about 80 DEG C to about 100 DEG C per hour up to at least 500 DEG C.</p>
