摘　　要：为解决随着工作面的推进和相邻工作面回收封闭导致通风量不足的问题,以某煤矿1017工作面为例,在研究其地质、瓦斯以及通风等基本情况的基础上,通过新增回风立井、新匹配通风机并扩大回风巷道断面面积等对通风系统进行改造。应用结果表明,经改造后,工作面的通风能力、负压能满足实际生产的需求。In order to solve the problem of insufficient ventilation due to the advancement of the working face and the recovery and closure of the adjacent working face,the ventilation system was modified by adding a new return air shaft,matching new ventilation fans and expanding the roadway cross-sectional area based on the study of the basic conditions of geology,gas and ventilation of the 1017 working face.After the renovation,the ventilation capacity and negative pressure of the working face meet the actual production requirements.

关 键 词：通风系统 负压 通风量 扩大巷道断面面积 需风量
