The CO/O2 def. ratio, CO content and alkene content are used for the indicators of spontaneous heating underground. Now, we discovered a new method of the ratio of alkanes.
The reliability of the new method was proved by laboratory experiments and on the site tests. When coal temperature rise slightly, the ratio of alkanes increase sensitively. Therefore, the ratio may become an excellent indicator of spontaneous combustion of coal.
