| Abstract: | Using the experimental system of coal spontaneous combustion to simulate the spontaneous combustion process of the coal sample from coal seam 7 in Longgu mine.In this experiment,the relationship between the change of oxygen concentration and the temperature and condition of coal is researched.The lowest oxygen concentration of nitrogen injection is also determined.It is pratical guiding significance to prevent coal spontaneous combustion by nitrogen injection. |
