Abstract
A process for the underground gasification of coal and carbonaceous materials in makes the customary lengthy preliminary task of establishing an underground interconnection between wells and cavities unnecessary. Instead, according to the invention, the circulation of gasifying agents and product gases is between one or more wells and the boundary of an underground generator (i.e. cavity system) through a reaction zone in the generator.
