摘　　要：随煤矿采掘深度增加,瓦斯治理越来越困难,利用合理的微生物来进行矿井瓦斯治理是一种新的尝试和思路。本文选取自主培养的甲烷氧化菌混合菌群液浸泡后的煤样、浸水煤样及原煤开展煤样瓦斯吸附解吸试验,试验研究结果发现,经过甲烷氧化菌混合菌群液浸泡后的煤样的瓦斯吸附量大于原煤的瓦斯吸附量,大于浸水煤样的瓦斯吸附量,分析试验数据得到代表煤样极限吸附量的瓦斯吸附常数a值也存在相同的规律。With the increase of coal mining depth, gas control is becoming more and more difficult, and it is a new idea and method to use reasonable microorganism to deal with mine gas. The gas adsorption and desorption experiments were carried out by using the coal samples soaked by self-cultured methane-oxidizing mixed microbial consortium and water and raw coal. The re- search results showed that the gas adsorption capacity of coal samples soaked by methane-oxidizing mixed microbial consortium was greater than that of raw coal and the gas absorption capacity of coal sample soaked by water was the smallest. The gas ad- sorption constant a, which represents the ultimate adsorption capacity of coal samples, also had the same laws.
