摘　　要：为保证3303长距离掘进工作面通风质量,首先分析通风参数,归纳通风工作问题,其次通过选择合理通风设备,如大直径风筒、异径风筒转换器等技术,优化完善通风管理制度,实现减少漏风、减小风阻、增加有效风量、工作面瓦斯浓度降低至0.1%以下的目标,满足长距离掘进工作面通风工艺要求。In order to ensure the ventilation quality of 3303 long distance tunneling face,firstly analyze the ventilation parameters and summarize the ventilation problems.Secondly,optimize and improve the ventilation management system by selecting reasonable ventilation equipment,such as large diameter air duct,soft belt with quick joint of air duct,reducing air duct converter,automatic switch of double fans and other technologies.The goal of reducing air leakage,reducing wind resistance,increasing effective air volume and reducing gas concentration of working face to less than 0.1% was achieved,and the requirements of ventilation technology for long distance driving face are met.
