摘要
针对高瓦斯矿井工作面瓦斯涌出和上隅角瓦斯积聚的现状,福达煤矿80208工作面采取了综合瓦斯治理措施,经对邻近层、本煤层、采空区和上隅角4个区域的抽放瓦斯,解决了工作面瓦斯超限问题,保证了其正常回采和安全生产。
To solve gas outburst on working face and methane accumulation around upper corners inhigh-gassy mine, comprehensive gas control measures were adopted on No. 80208 working face in Fuda Mine. Gas drainage was used in this seam, the adjacent seam, gobs, and the upper comers to approach the gas over-limited emission, which guaranteed normal mining and safe production of the mine.
