| Abstract: | The pyrolytic experiment was conducted with the collected coal samples. A gas chromatograph was used to measure the oxygen content of coal sample under different pyrolytic temperatures. The paper analyzed the law of oxygen with the temperature variation. The paper had got the quantity relationship between the oxygen consumption rate and the temperature. The oxygen content, the oxygen law and the relationship can be applied to ascertain the stage of the coal spontaneous combustion, which could scientifically control the coal spontaneous combustion and could provide the decision reference to prevent the coal spontaneous combustion occurred. |
