块煤瓦斯吸附动力过程的实验研究

Experimental Study of the Dynamic Process of Block Coal Methane Adsorption

采用大块煤为实验煤样，实验研究了块煤吸附瓦斯过程中瓦斯压力随时间的变化关系。实验分析得出了煤对瓦斯的吸附过程也是一个渗流一扩散的动力过程。

In this pater, large block coal is taken as the experimental coal sample for an experimental study of the relationship of methane pressure varying with time during block coal methane adsorption. It is known from the ex penment and analysis that the block coal methane adsorp non process is also a permeation - diffusion process.
