Development and Current Situation of Study on Theory of Methane Adsorption on Coal

From aspects of the adsorption mechanism, adsorption experiment method and standards, application of adsorption isotherm method, the paper has summarized and appraised the theory research course and achievement of methane adsorption on coal at home and abroad and analyzed existing problems in Chinaʹs coal reservoir adsorption theoretical research and experiment method. Finally the paper probed into the study of the development trend and problems need to be resolved.
