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。
Experimental study on the influence of coal gas permeability on gas permeability under different temperatures was carried out by using the laboratory self-made coal seam gas dynamic simulation system. The method and process of coal permeability experiment under the effect of temperature are expounded, and the gas seepage law of coal seam under temperature change is obtained. The experimental results show that under different temperatures, the permeability of coal decreases exponentially with the increase of gas pressure. Under a certain gas pressure, the permeability of coal decreases with the increase of temperature.
