In Ukraine, the basic direction of the restructurization is the closing of enterprises. Due to the closing of mines, the coal production has been reduced approximately by 5 mln tons. By the evaluations of geologists, more than 900 mln tons of the industrial reserves of coal remain on the closed mines.At the present time, the sharp increase of a share of coal in the fuel-energy balance of the country is a very urgent problem. Underground gasification of coal in its natural bedding can be one of the most efficient and ecologically clean methods to involve the solid fuel in the process of generation of the thermal and electrical energy.The purpose of the article is to offer a means of underground gasification of coal (UGC) as the basic one to obtain the products of its processing, which are required in various sectors of state’s economy. The existing principles of the new UGC technology make it possible to assert that it will be not only environmentally acceptable, but also economically competitive in comparison with the conventional shaft mining of coal.The realization of projects on the transfer of restructured mines into the category of those producing gas will allow one to decrease the budgetary expenditures on the closing of unpromising mines approximately by 50–60% and to decrease the social load on mines with a labor employment of 40–50 miners per one borehole.
