The mathematical model of gas explosion during coal mine fire sealing was set up, and was verified by the "8.21" gas explosion accident induced by coal bed spontaneous combustion in one coal mine of Hegang Branch. The gas flow field, temperature field and pressure field as normal ventilation and fire zone during fire sealing were analyzed. And then, the dangers and characters of gas explosion induced by coal bed spontaneous combustion were analyzed.
