| 摘 要： | 通过对新疆煤田火区火风压物理过程的分析，提出煤田火区火风压由地上、地下区域组成.地上、地下区域火风压主要是由空气柱内外温度差形成的密度差导致对流作用产生的.同时认为地下区域箱体内存在烟气的多变膨胀效应.基于上述作用机理，提出了新疆煤田火区火风压计算模型，并对火区状态系数C进行了分析. 从确定火区地面覆盖层厚度和估算火区温室效应气体排放量2个方面对该模型进行了应用分析， 初次提出了火区温室效应气体排放量的估算模型.

| Abstract: | Study on the process of the fire-heating airflow development due to spontaneous combustion in Xinjiang coal field reveals that the fire-heating air pressure(FAP) is composed of the upper-ground and underground sections,energized by the density difference arose from air temperature differences.Based on the above mechanism,a mathematic model for FAP calculation was put forward.The covering thickness for open coal fire control was analyzed and the green-house gas emission from coal field fire was estimated. |

| Keywords: | coal-field fire fire-heating air pressure(FAP) green-house gas emission |
