摘　　要：论述了曙光矿穿层钻孔的布置方式及单孔瓦斯的抽采情况,对该矿1216综采工作面初采初放前施工瓦斯抽放穿层钻孔,在初采初放后进行瓦斯抽放效果验证,得出该矿孤岛工作面裂隙带钻孔终孔位置的合理层位,确保工作面初采初放期间瓦斯抽放有效,为以后工作面抽放钻孔设计提供数据依据。Discusses the arrangement mode of drilling through layer and the extraction gas in Shuguang coal mine. The drilling before initial mining and caving of tlie No. 1216 fully meface is carried out. The results show that the gas drainage is effective, and the experience design in future working face.
