针对目前实验室研究含瓦斯煤渗吸效应的缺陷,搭建等压实验平台,在实验系统压力恒定条件下,对不同水分自然流入含瓦斯煤后的渗吸效应进行测试,并与非恒压条件下含瓦斯煤渗吸效应进行对比。结果表明:随着含水率的增加,渗吸量逐渐增大到稳定的数值,但渗吸量的增加幅度逐渐变小;渗吸速度包括快速增加、缓慢持久、衰减至0 3个阶段;等压条件下比非等压条件下的渗吸量和渗吸率高。
In view of the current laboratory studies on the gas imbibition effect of methane containing flaws, set up an isostatic test platform, under constant pressure in the experimental system conditions, the different infiltration of natural moisture into the coal gas after the imbibition effect test and with non-constant pressure conditions Under the effect of coal gas seepage absorption contrast. The results show that as the moisture content increases, the amount of imbibition gradually increases to a stable value, but the increase of the amount of imbibition decreases gradually. The rate of imbibition increases rapidly, slowly and decay to 0 3 stages. Under pressure conditions than the non-isobaric conditions, the amount of imbibition and permeability rate.
