摘要
介绍了通过实验方法测定在煤与瓦斯突出过程中的温度变化,测定结果证实了在煤与瓦斯突出过程中,瓦斯的膨胀做功过程并非绝热过程,而是一个接近于等温过程的多变过程。
An experimental method is introduced to measure the temperature variation of coal and gas outburst. The results of laboratory experiments and the theoretical analysis has proven that the process of gas expansion in the course of coal and gas outburst is not an adiabatic process but a polytropic near isotherm process.
