摘要
以煤层瓦斯径向流动理论模型和现场实际情况为基础,对影响地面钻井瓦斯抽采量的因素进行分析,并利用改进的层次分析法对其进行重要性排序,根据潘三矿1#和4#地面钻井抽采被保护层开采卸压煤层瓦斯抽采量的记录数据,分析影响地面钻井瓦斯抽采效果的主要因素。
According to the coal bed gas radial flow theory model and actual situation,some factors influencing gas extraction of borehole are analyzed,and whose importance ranking can be made by using improved analytic hierarchy process(AHP). In addition,on the basis of the data of gas extraction by surface borehole No. 1 and No. 4 drilling the coal seam of its pressure released by mining for the factors of gas drainage in the surface borehole.
