Abstract

A numerical model which describes coal underground gasification heat and mass transfer processes was formulated. Numerical studies let to define a generated gases composition in dependence to gasification products temperature and pressure, and forced in heated gas composition. A combustible gas discharge composition versus forced in oxidizer components concentration functional connections are obtained, where dry air, different proportion mixture of oxygen, nitrogen and water vapor are forced in oxidizer components. It is found that a low-temperature gasification regime is occurred if an oxidizer contains no more than 15% of oxygen. If oxygen concentration in an oxidizer is more than 15% a high-temperature gasification regime is occurred, and a combustible gas discharge is increased.
