局部高瓦斯带炮采放顶煤工作面在组织生产时,时常会出现瓦斯超限现象,严重制约着安全生产,通过采用打瓦斯释放钻孔、加强放炮管理等多种手段,降低了回风流中瓦斯的浓度,保证了工作面的安全生产。

The partial high gas belt artillery picks puts goes against the coalworking surface when the organization production, often can appear tbegas ultra to limit the phenomenon, seriously is restricting the safetyin production, through uses hits the gas release drill hole,strengthens fires a gun the management and so on the many kinds ofmethods, reduced returns to the wind lanecenter the gas density, has guaranteed theworking surface safety in production.
