摘要:
为研究外加水分条件下受载含瓦斯煤体的渗吸特性，利用自主设计的含瓦斯煤体等压渗吸实验装置对煤体中水分及瓦斯的运移进行连续监测，并在瓦斯压力恒定不变的条件下研究覆压及外加水分对煤体渗吸距离、渗吸速度以及瓦斯置换量的影响。结果表明：水分在煤体中的渗吸距离随时间增长先是快速增加，而后缓慢增大。在相同外加水分条件下，相同时刻水分的渗吸速度随覆压增大而增大；在相同覆压条件下的煤体，相同时刻水分的渗吸速度随外加水分的增大而增大；渗吸过程中水分置换出来的瓦斯量随时间变化分为3个阶段，在第1个阶段覆压和外加水分的变化对瓦斯置换量影响不大，之后的2个阶段瓦斯置换量随着外加水分和覆压的增大而增大，并逐渐达到1个极限值。
Abstract:
In order to study the imbibition characteristics of loaded coal containing gas under the condition of additional moisture content,the self-designed isobaric imbibition experimental device of coal containing gas was used to continuously monitor the migration of moisture content and gas in the coal,and the influence of overburden pressure and additional moisture content on the imbibition distance,imbibition rate and gas replacement amount under the condition of constant gas pressure was studied.The results showed that with the increase of time,the imbibition distance of moisture content in coal increased rapidly at first and then increased slowly.Under the same condition of additional moisture content,the imbibition rate of moisture content increased with the increase of overburden pressure at the same time.For the coal under the same overburden pressure,the imbibition rate of moisture content increased with the increase of additional moisture content at the same time.In the process of imbibition,the amount of gas replaced by moisture content could be divided into three stages over time.In the first stage,the change of overburden pressure and additional moisture content had little influence on the gas replacement amount.In the next two stages,the gas replacement amount increased with the increase of additional moisture content and overburden pressure,and gradually reached a limit value.
