| Abstract: | Coal samples were collected from Xinglongzhuang Mine.The thermal gravity analysis(TG) on the coal samples was conducted with the test conditions of different temperature going up rate,different oxygen density and different particles.75 related TG and DTG curves were obtained from the analysis.With the analysis,7 characteristic temperatures of the coal spontaneous combustion process were obtained.The related temperature ranges were set,which would be the certain basics for the study of the coal spontaneous oxidization. |
