摘要
为了研究告成矿三软煤层煤样的瓦斯解吸规律,在试验设定条件下对该矿2组不同破坏程度具有典型豫西三软煤层特征的煤样进行了瓦斯吸附解吸过程模拟测试。分析计算了瓦斯解吸过程中的累积瓦斯解吸量和在5、10、30和120 min各个时间段内的解吸参数。
In order to research the gas desorption laws of coal sample from three soft coal seam of Gaoeheng coal mine,the gas desorption process simulation test is made under certain experimental conditions of two different westren henan calculated and damage degree coal samples from this coal mine with typical feature of three soft,the cumulative amount analyzed in four time periods of 5 of gas desorption and the desorption parameters are min, lO min,30 min,120 min.
