Abstract：According to the distribution of loose coal in the gates of fully mechanized longwall top-coal caving face, a 2-D model for spontaneous combustion of coal is developed to predict the self-ignition of loose coal at the gate in fully mechanized longwall top-coal caving technology. The numerical calculation method is put forward. Finally, the tailgate of workface 4308 in Dongtan Coal Mine is simulated numerically. Self-ignition of loose coal is predicted.
