摘要
专门针对瓦斯解吸及吸附作用与煤岩形变的相关性做出实验认证,条件是恒压恒温,利用物理上的排水法间接获得瓦斯体积,又由于解吸量与吸附量是一对互逆过程,那么即可利用回归分析便能够算出朗格缪尔体积常数a以及压力常数b,进而把所获得数据进行拟合分析,得到了体积变化与解吸量的关系式,最终分析出瓦斯解吸及吸附作用和煤岩体积形变的定量关系。
The experiment for gas desorption and adsorption and the correlation ot coal and rock deformation experiment certification, on condition that constant pressure constant temperature, use physical drainage method to obtain the gas volume indirectly, due to the adsorption desorption quantity and is a reciprocal process, then can use regression analysis to calculate the constant volume and constant pressure b, then the data received by fitting analysis＇, obtained the relation between the volume change and desorption quantity a and pressure-constant b. Finally analyze the gas desorption and adsorption of coal and rock deformation volume quantitative relationship.
