The examined coals can be the raw material for underground coal gasification. Measurements were carried out under isothermal conditions at a high pressure of 4 MPa and temperatures of 800, 900, 950, and 1000°C. Yields of gasification products such as carbonmonoxide and carbon dioxide, hydrogen andmethane were calculated based on the kinetic curves of formation reactions of these products. Also carbon conversion degrees are presented. Moreover, calculations were made of the kinetic parameters of carbon monoxide and hydrogen formation reaction in the coal gasification process. The parameters obtained during the examinations enable a preliminary assessment of coal for the process of underground coal gasification.
