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 The trend of temperature change during coal and gas outburst was theoretically analyzed and verified in laboratory. It is considered that during the process of coal and gas outburst, the temperature of coal increases due to the release of elastic energy by the crushing of ground stress, while the temperature decrease is caused by desorption and expansion of gas. Its change is firstly increased, then decreased and continuously changed, and according to the gradient of coal body temperature, the prediction of gas outburst can be carried out
