Abstract：In order to objectively determine the spontaneous combustion risk of coal in gob, using entropy weight theory for analyzing the weight of the evaluation indexes can effectively avoid the influence of subjective factors in the analysis process so as to obtain a more objective weight coefficient. An entropy weight extension comprehensive evaluation model was established, and by taking the spontaneous combustion situation of residual coal in the gob in a mine as examples, the prediction accuracy of this method was verified and it was consistent with the actual situation. The research showed that the entropy weight extension comprehensive evaluation method can be used to better predict the spontaneous combustion of residual coal in the gob, it provided a certain basis for the division of coal spontaneous combustion“three zone”, and its calculation is simple, so this research result has the instructive significance to the actual production.
