煤与瓦斯突出过程中影响温度变化的因素分析

The theoretical analysis of the influencing factors about temperature change in the process of coal and gas outburst

利用多元回归分析的方法对煤与瓦斯突出过程中温度变化的影响因素进行了分析 ,认为在煤体破裂阶段使煤体温度变化的主要影响因素是地应力 ,其次是瓦斯压力 ,然后才是煤体强度 .地应力对煤体温度变化的影响大约是瓦斯压力的 5～ 6倍 .

Using the regression multianalysis method, the influencing factors about temperature change, which is brought in the process of coal and gas outburst, are analyzed. It believes that the main factors, which make the coal temperature changed at the stage of coal cataclysm, are geologic stress, gas pressure and coal body intensity. Among them, geologic stress is the most important factor, gas pressure is the secondly important, and coal body intensity is the lastly important. Now the affection of geologic stress to coal temperature change is about 4～5 times than the affection of gas stress.
