The underground coal gasification (UCG) process represents a modern and effective coal mining technology that enables coal energy extraction through thermic decomposition. The coal is transformed into syngas by oxidizers (, air, technical oxygen, or water steam) and is injected into a georeactor. The produced syngas is exhausted on the surface, where it is transformed into the desired form ...

In underground coal gasification, unmineable coal is converted into clean gaseous fuel. The UCG process starts in coal seam, proceeds to interior of the coal to form cavities and converts coal into gaseous product leaving the solid ash beyond. As the gasification process proceeds, the cavity grows 3dimensionally and nonlinearly.
