摘　　要：甘庄煤矿8303工作面采用"U"型通风方式,采空区漏风通道两端风压差造成采空区内部瓦斯涌出,从而导致工作面上隅角瓦斯积聚。针对这一问题,通过分析瓦斯来源及造成浓度超限的原因,提出采用均压通风技术治理上隅角瓦斯的方案。根据瓦斯浓度变化情况可知,均压通风在8303工作面上隅角瓦斯治理中取得了很好的效果。＂U＂ style ventilation mode is used on 8303 working face of Ganzhuang coal mine.The pressure differences in both ends of the gob air-leaking passage create the gas emission from the interior gob,which leads to the gas accumulation in the upper corner of the working face.Aiming at the problem,through analyzing gas sources and concentration overrun reasons,the proposal of controlling upper corner gas is proposed by using pressure balancing ventilation technology.It is known from the gas concentration changing situations that pressure balancing ventilation achieved good results in upper corner gas control of 8303 working face.
