摘要
通过对唐山矿Y484综放工作面通风压力与瓦斯涌出变化关系进行摸索和分析,找出了工作面瓦斯涌出与大气压影响的规律,通过建立工作面自动调整通风压力装置,有效地抑制了采空区瓦斯涌出,降低了Y484工作面风流瓦斯浓度,消除了瓦斯异常涌出对正常生产活动的影响,为工作面的安全高效生产提供了可靠保障。
Based on the analysis of relationship of ventilation pressure and gas emission of Y484 fully mechanized working face,the law of gas emission and barometric pressure was found,automatic voltage regulating device was set to control gas emission in goaf,reduced the gas content of Y484 gas content,removed the side effect of gas emission,provided safe mining.
