中文摘要：
利用煤田露头火区模拟实验装置,通过对煤火燃烧过程中出风裂隙内气体温度的监测,发现裂隙内气体的温度沿裂缝逐渐降低并成指数衰减分布。通过分析得到火区裂隙温度的分布方程并计算得到了裂隙内火风压分布方程,得出煤田火区火风压的影响因素主要有自燃煤层温度、自燃深度和裂隙倾角。
英文摘要：
The coalfield outcrop fire area simulation experiment device is used to monitor the temperature of gas in the wind out crack,finding that the temperature of the gas decreases gradually along the crack and shows exponential decay distribution. The equation of temperature distribution and the fire wind pressure distribution are obtained by analyzing. By formula,the influence factors of fire wind pressure is mainly composed of spontaneous combustion temperature,the depth of the coal seam and the crack angle.
