Regenerative method of underground gasification process of coal. [Heating value of 900-1000 Kcal/m/sup 3/ increased to 1300-1400 Kcal/m/sup 3/ by increasing O content to 23%; with O and steam it was 2500 Kcal/m/sup 3/; gas composition of CO/sub 2/ 13. 58, O 0. 22, CO 6. 32, H 58. 5, CH/sub 4/ 4. 28, N 17. 1%]

The chemical reactions taking part in an underground gas producer can be divided into exothermic and endothermic processes. The exothermic reactions entail the evolution of large heat quantities. Practice shows that during the combustion and gasification of coal seams a large amount of heat is produced, heating and partially melting the immediate overburden. The problem is to utilize this heat for increasing the quality of the product gases.
