| 摘 要： | 运用实验室自制研究的煤层瓦斯动力模拟系统,进行了煤体在不同温度作用下对瓦斯渗透性影响的实验研究。阐述了温度作用下煤渗透性实验的方法与过程,得到考虑温度变化情况下煤层瓦斯渗流规律。试验结果表明:在不同温度条件下,煤的渗透率随气压的增大而呈指数形式减小;在一定的气体压力下,煤体的渗透率随温度的增加而减少。

| Abstract: | The gas permeability of coal under different tempteratures is studied by means of self-made coal gas dynamic simulation system.The way and process of coal gas permeability experiment under the influence of temperature are demonstrated.The law of gas permeability under different temperatures is obtained.The results show that the coal gas permeability decreases as the air pressure increases under different temperature;the coal gas permeability decreases as the temperature increases under certain air pressure. |
