浅孔抽放技术在高瓦斯综采面的应用

Application of draining methane by shallow boreholes technology in full-mechanized mining face with high gas

分析了浅孔抽放机理和瓦斯运动特征,介绍了浅孔抽放技术的参数设计、施工技术和抽放工艺,解决了瓦斯对工作面生产的制约和影响,降低了回风流中的瓦斯浓度,确保了安全生产。

The paper analyses the mechanism and law of gas movement of draining methane of shallow boreholes, introduces parameter design constructing technology and drainage technology of draining methane of shallow boreholes. It has resolved restraint and effect on the gas to production, reduced the gas density of wind tunnel and ensured safety production.
