摘　　要：针对传统的地面抽采钻孔技术在薄煤层抽采效果差的问题,通过理论分析及现场试验,找出了抽采效果差的原因,研制出了挂管器,成功应用在小青矿W2718薄煤层工作面在7个地面抽采钻孔上,取得了明显的抽采效果,为集团公司薄煤层工作面地面瓦斯抽采提供了一个很好的借鉴经验。To solve the problem of poor drainage effect of traditional surface drilling technology in thin coal seams,the factors for the problem are figured out by theoretical analysis and site test.Pipe-hanger is developed and successfully applied in 7 surface boreholes in W2718 working panels of Xiaoqing coal mine.The application has achieved significant effect,and provided a good reference to the surface gas drainage in thin coal seams for Tiefa Group.
