Physical and technical features of underground gasification of coal pillars

The results of calculations using models convincingly demonstrate that the ISUCG technology is capable of resolving the set task of recovering coal reserves lost at present in worked-out mines.
With proper application, ISUCG technology, retaining all the merits of injection technique (high efficiency, low cost of energy carrier, excellent ecological factors, elimination of hard underground work, etc.), will become a highly efficient technique for recovering coal reserves lying in complicated mining and geological conditions.
The injection-suction system of underground coal gasification is now being tried out on steep Kuzbass (Kuznetsk Basin) coal seams under the conditions prevailing at the Yuzhnyi Aban station of Podzemgaz using a specially designed experimental module.
