低瓦斯矿井U型通风采煤工作面瓦斯综合治理

低瓦斯矿井U型通风采煤工作面上隅角瓦斯治理是矿井通风瓦斯管理的难点,对采煤工作面细化通风管理并采用上隅角埋管或插管抽放,可有效解决采煤工作面上隅瓦斯超限问题,对于类似的低瓦斯矿井U型通风系统的采煤工作面上隅角瓦斯治理有非常重要的借鉴意义.

Gas Comprehensive Treatment of U Ventilation Coal Mining Face in Low Gas Mine

The upper corner gas control of the U ventilation coal mining face in low gas mine is the difficulty of gas management in mine ventilation,refines ventilation management of the coal mining face and uses the upper corner laying pipe or spile drainage,can effectively solve gas over-limitation of the upper corner in the coal mining face,for the upper corner gas control of coal mining face similar U ventilation system in low gas mine has very important significance.
