| Abstract: | The gas adsorption theory of monomolecular layer polymolecular layer of coal was presented. Adsorption of coal bed to different gases was compared. Adsorption capacity of coal bed to different gases was acquired. The principle and advantages of displacing coal-bed methane by injecting CO2 and N2 were expounded. It had proven the feasibility of displacing coal-bed methane by injecting CO2 and N2. |
