TECHNOLOGICAL SCHEME FOR UNDERGROUND GASIFICATION OF COAL AND HARD HOUSEHOLD WASTES
Abstract
The idea of underground coal gasification is connected with the name of Mendeleev 120 years ago. But its practical realization starts during the 30th years of the previous century and continues up to now. There is not any technical or technological problem to perform gasification as a method of processing hard household wastes. In combination with recycling of part of the wastes and utilization of gaseous products of gasification for energy production, this method could be very effective and attractive. If we suppose possible underground gasification of coal and wastes, in the article is presented a technologic scheme to use wastes for filling the mined- out area. The last stage of mine operations is underground gasification of coal pillars and deposited hard household wastes. Conceptual technological scheme for practical realization of the idea in Choukourovo mine pit, Bulgaria is presented.
