This paper selected Chengzhuang Mine No.9coal as anthracite samples. Effect of temperature on coal oxygen adsorption at 25,30,35,40 ℃ conditions was studied by adsorption constant measuring apparatus. The results show that, under the condition of critical spontaneous combustion temperature(25~40 ℃)and lower pressure(p≤2.5MPa),the adsorption of coal for oxygen has an inhibitory effect with the increase of temperature. The fitting effect of Langmuir model is better in the temperature range of 25~35 ℃,and worst at 40 ℃;the fitting effect of Brunauer-Emmett-Teller is the worst at 25 ℃,and the fitting error becomes smaller with the increase of temperature while fitting effect is getting better and better; the average relative error of the Dubinin-Radushkevich model model is smaller and the standard deviation is the smallest in the experimental temperature of 20~40 ℃,Dubinin-Radushkevich model model explains the adsorption mechanism of anthracite is the most reliable and authentic. This research can provide a theoretical basis and reference for the air for coal-bed methane.
