Experimental Study on the Index Gas Based on Characteristic Temperature of Coal Low-temperature Oxidation
The optimal index gas in different phases of low — temperature coal oxidation is studied by coal low temperature warming oxidation experimental system and gray relational theory.Through the low temperature oxidation experiments, the first and second characteristic temperatures of the coal samples were determined, and the process of low - temperature oxidation of coal samples was divided into three phases by the characteristic temperature points. According to the relative grey correlation method, the grey correlation degree between different kinds of gases in each oxidation phases and temperature was respectively calculated, and the gas which the correlation degree was the highest was taken as the optimal indicator in the stage.The results of this paper can provide the basis for coal mine choosing index gas scientifically and reasonably.
