采用容量法对延迟突出煤吸附甲烷的特性进行了研究，结果表明：吸附常数ａ较大且ｂ较小时，易发生延迟突出；延迟突出煤的吸附／解吸动力学过程遵从吸附／解吸－扩散控制模型等，延迟突出煤样的放散能力较弱，导致了煤瓦斯突出的延迟。
The volumetric method was used to study the characteristics of delayed outburst coal adsorption on methane. The results show that the delay is prominent when the adsorption constant a is large and b is small. The kinetics of adsorption / desorption kinetics follows the adsorption / desorption / diffusion process Model and so on, the delayed release of coal samples is weak, leading to the outstanding delay of coal gas.
