摘要
8404综采工作面采用U型通风方式,在开采过程中经常出现上隅角瓦斯积聚现象,给工作面的安全生产带来了隐患。通过该工作面瓦斯来源和积聚原因的分析,确定采用风幛法和高位瓦斯钻孔抽放相结合的方法对上隅角瓦斯进行治理,较好地解决了上隅角瓦斯积聚问题,为该工作面的安全、高效开采奠定了基础。
Gas accumulation often occurs at the upper corner due to the U--shaped ventilation method in 8404 fully mechanized working face,which can bring hidden trouble to safety production. By analysis of the gas source and accumulation causes, the author suggests the application of brattice method with borehole drainage of high--position gas, which can solve the problem of the gas accumulation at upper corner and lay the foundation for the safe and efficient mining.
