摘要：
the paper determines and calculates the parameter of coal temperature distribution rule and oxidation thermal intensity in the stage of low temperature oxidation of radiating heating, builds the mathematic model with 5 key parameters which affect the coal spontaneous combustion, newly defines a probability function to descript the coal spontaneous combustion dangerous degree, then puts forward a quantitative evaluating parameters: the different value of the indicator represents different dangerous area, a fully extinguished zone, a base extinguished zone, a heat dissipation zone and a oxidation of radiating heating zone. The results have a good accordance with the actual observations value.
