摘要
通过瓦斯抽排井将井下预抽瓦斯输送至地面加以综合利用,成为瓦斯治理的有效方法之一。瓦斯抽排井由于直径小,深度大,只能采用机械施工,反井作为一种高效的机械井筒施工技术,近年来成为瓦斯抽放井施工的常用工艺之一。介绍了目前瓦斯抽放井施工常用的机械施工工艺,并对反井施工的工艺、优缺点做了详细介绍,为瓦斯抽排井确定施工方案提供参考。
One of the best methods of governance in gas is pumping the gas to the ground and Utilization of the gas collected underground through a gas drainage shaft.This shaft can only use mechanical construction, due to the small diameter and the large depth.As an efficient mechanized borehole construction methods, the raising-boring machine become a common method of the gas drainage shaft construction in recent years. The current gas drainage shaft construction techniques commonly used in machinery construction are introduced. Then introduce the construction details and advantages and disadvantages of the Raising-boring construction. The Conclusion can provides a reference to determine the gas pumping wells construction program.
