摘　　要：针对高瓦斯工作面,开采期间采空区瓦斯大量涌向工作面,造成工作面上隅角回风流瓦斯超限的实际问题,根据采空区内瓦斯流动的规律,合理布置抽放钻孔,降低工作面及回风流瓦斯涌出量,达到安全生产的目的。During mining activities in high gas coal seam, the gas concentration in the comers and air returning way of face often exceeds limit. In view of this actual problem, according to the gas flow rule in gob, reasonablg arrange the Bore- hole so as to reduce gas and achieve the goal of safety in production.
