摘　　要：根据火灾巷道的具体边界条件和烟气传播介质特性建立了辐射换热的热流传输方程,对巷道中火灾烟气流场的能量传输方程进行了修正,得出在矿井巷道火灾烟气流场的理论计算中,辐射换热是不可忽略的重要因素,可为矿井灾变时的救灾决策提供更为准确的科学依据.The transmission equation of the heat flow of the thermal radiation transfer was built up by the material confined condition and the medium characteristic of the mining fire propagated.The energy transmission equation is corrected for the mining fire flow in mining. The results showed that the thermal radiation transmission is impossibility ignored in theory calculation for the equation of the energy transimission of the mining fire flow in mining,accurater and more scientific foundation is provided for the policy decision of the providing disaster relief when mining fire.
