煤层瓦斯不均衡分布的特性使得低瓦斯矿井综放工作面中，经常出现局部瓦斯涌出的不良现象。瓦斯异常给矿井的安全生产造成极其严重的威胁。鉴于此，首先对低瓦斯矿井综放工作面瓦斯异常的问题进行了初步研究，并在此基础上，采取有效的措施来控制瓦斯超限，保证综放工作面回采的安全性，从而进一步确保低瓦斯矿井的安全生产。
煤層瓦斯不均衡分佈的特性使得低瓦斯礦井綜放工作麵中，經常齣現跼部瓦斯湧齣的不良現象。瓦斯異常給礦井的安全生產造成極其嚴重的威脅。鑒于此，首先對低瓦斯礦井綜放工作麵瓦斯異常的問題進行瞭初步研究，併在此基礎上，採取有效的措施來控製瓦斯超限，保證綜放工作麵迴採的安全性，從而進一步確保低瓦斯礦井的安全生產。
