摘要
间歇性抽采是指在进行瓦斯抽采过程中,对抽采浓度较低的钻孔进行关闭,降低抽采效果差的钻孔对其他钻孔的影响,从而提高整个工作面的抽采效果。以保德煤矿三、五盘区的8条巷道为例,分别进行间歇性抽采实验;通过实验效果分析,提出间歇性抽采周期为10天,为矿井提高抽采效果提供了依据。
The gas intermittent extraction refers to improving the gas extraction efficiency of the whole working face by closing low concentration drillings during the process of gas extraction. The actual tests of gas intermittent extraction were carried out respectively in 8 roadways of third panel and fifth panel of Baode coal mine. The test results show that the reasonable cycle of gas intermittent extraction is ten days,which provide the basis for improving the effect of gas extraction.
