Abstract: Taking the raw coal samples of Inner Mongolia lignite, Datong bituminous coal and Heilongjiang anthracite with different metamorphic degree and treated with composite inhibitory solution as test objects, the inhibition effects of composite inhibitors on three kinds of coal samples were compared through experimental measurement and dynamic analysis. The results show that the composite inhibitors can effectively inhibit the oxidation reaction of Datong bituminous coal and increase the activation energy of coal body. The inhibition effect is much higher than that of the other two coal samples.
