Based on the distribution state of the combustibles and the scale of the fires in underground mines, mine fire sources are divided into two types in this paper,namely, fixed point fire source and movable linear fire source. By analying a lot of ex periment results of mine fires, the authors studied the combustion characteristics of the two types of fire source, and have set up their mathematical models. The models have further been applied to calculate the concrete mine instances and the obtained re sults corresponded with the reality.
