| 摘 要： | 瓦斯抽放井是瓦斯治理和煤层气开发利用的一种有效手段。通过彬长矿区大佛寺煤矿5口大口径瓦斯抽放井的施工实践，探索出瓦斯抽放井在井位选择、防斜保直、扩孔、井管牵引和固井方面的一些工艺技术，其成熟的做法对地质条件类似的矿区具有一定的借鉴意义。

| Abstract: | Gas drainage well is a kind of effective means in gas governing and CBM exploitation and utilization. Through construction practices of 5 large-diameter gas drainage wells in Dafosi coalmine, Binchang mining area, explored some industrial arts and technologies on gas drainage well positioning, deflection prevention, reaming, casing traction and well consolidation. Its successful practices have certain referential significance for mining areas with similar geological conditions. |
