摘　　要：为探索采动稳定区瓦斯地面开发技术,首次在松藻矿区开展了采动稳定区瓦斯地面抽采试验项目,完成地面井2口。通过钻井实践,掌握了松藻煤矿采动稳定区上覆岩层特点,总结了采动稳定区地面井难点及对策,初步形成一套适合松藻煤矿采动稳定区地面井的施工工艺,给松藻采动稳定区后续地面井施工提供参考。In order to explore the gas extraction technology in mining- affected stable region,ground holes are completed to pump coal- bed methane in stable mining- affected region in Songzao Coal Mine for the first time. According to the drilling practice,the strata characteristics over stable mining- affected region are obtained,the drilling difficulties and corresponding measures are discussed,the reasons of drilling accidents are analyzed. At last,the drilling technique for stable mining- affected region in Songzao Coal Mine is formed,which provides the conference for further drilling operation in the district.
