| 摘 要： | 从理论上分析了煤与瓦斯突出过程中温度的变化趋势，并在实验室对其进行了实验验证，认为在煤与瓦斯突出过程中，煤体温度的升高是由地应力破碎煤体使弹性能释放造成的，而温度降低则是由于瓦斯气体解吸和膨胀造成的。其变化是先升高后降低并连续变化的，根据煤体温度变化梯度可以进行瓦斯突出的预测预报。

| Abstract: | The varying tendency of coal temperature during the process of coal and gas outburst is analyzed in terms of theory and validated by laboratory testing. It is proved that during the process of outburst, the rise of coal temperature is due to the release of elastic energy while the coal is cracked by crustal stress, and the decrease of coal temperature is due to the desorption and expansion of gas. The coal temperature varies continuously with the tendency so that it rises firstly and decreases subsequently. So based on this varying tendency of coal temperature, the outburst of gas can be predicted. |
