The characteristics of coal surface pore surface area were analyzed by mercury injection test so that we can obtain the types and distribution of different functional groups on coal sample surface through the method of infrared spectrum experiment and theoretical analysis. The physical adsorption processes and calorific values between different functional groups and CH4 were studied based on different functional groups constructed by molecular simulation software so that we can put forward the coefficient concept of heat release rate in which can further perfect the adsorption theory of coal gas.
