【摘要】：針對(duì)目前實(shí)驗(yàn)室研究含瓦斯煤滲吸效應(yīng)的缺陷,搭建等壓實(shí)驗(yàn)平臺(tái),在實(shí)驗(yàn)系統(tǒng)壓力恒定條件下,對(duì)不同水分自然流入含瓦斯煤后的滲吸效應(yīng)進(jìn)行測(cè)試,并與非恒壓條件下含瓦斯煤滲吸效應(yīng)進(jìn)行對(duì)比。結(jié)果表明:隨著含水率的增加,滲吸量逐漸增大到穩(wěn)定的數(shù)值,但滲吸量的增加幅度逐漸變小;滲吸速度包括快速增加、緩慢持久、衰減至0 3個(gè)階段;等壓條件下比非等壓條件下的滲吸量和滲吸率高。
[Abstract]:Aiming at the defects of the laboratory research on the permeation effect of gas-bearing coal at present, an isobaric experimental platform was set up. Under the condition of constant pressure of the experimental system, the permeation effect of different moisture naturally flowing into the gas-bearing coal was tested. The results show that: with the increase of water content, the amount of permeability gradually increases to a stable value, but the increasing range of infiltration capacity becomes smaller, and the speed of infiltration increases rapidly, and the effect of gas absorption on coal under the condition of non-constant pressure is compared. At the same time, the amount of osmotic absorption and the rate of osmotic absorption under isobaric condition are higher than those under non-isobaric condition.
