ABSTRACT
/Full article available only in Bulgarian language/

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.
