Abstract：In order to further study the effect of temperature on the methane-adsorbing capability of coal, based on the mechanism about the adsorbing and desorption of coal, twenty nine groups of experiments for the effect of temperature on the methane-adsorbing capability of coal are obtained by many researchers for recent decades are investigated. The results and data obtained through the experiments are summarized. From the view of probability theory and mathematical statistics, the results from the experiments are analyzed. The regularities on the effect of temperature for the methane-adsorbing capability of coal are obtained. The function relationship formulas among adsorption quantity, temperature and Langmuir adsorption constant are fitted out. The problem in urgent experiments is that experiments standard and condition are not uniform, and the future research directions are the relationship between Langmuir adsorption constant and temperature, especially the relationship between Langmuir constant and temperature. The achievements provide a theoretical basis for gas disaster prevention and coal bed methane development.
