摘　　要：薛虎沟煤矿2#浅埋深复采煤层回采面回撤期间,采用局部通风机通风时,受回撤通道断面影响,支架搬运车经常刮扯风筒,导致工作面供风不稳定。经过研究,决定采用负压通风的方式,形成回风通道,保证工作面风量满足回撤需要。与局部通风机供风相比,通风系统稳定性更高,工作面运输通道有效断面更大,回撤时间大幅缩短。During the withdrawal period of the 2#shallow burial depth re-mining coal seam in Xuehugou Coal Mine,when local ventilation fans are used for ventilation,the support truck often pulls the air duct due to the influence of the withdrawal channel section,resulting in unstable air supply to the working face.After research,it is decided to adopt negative pressure ventilation to form a return air channel and ensure that the air volume of the working face meets the withdrawal needs.Compared with the air supply of local ventilation fans,the ventilation system has higher stability,larger effective section of the working face transportation channel,and significantly shorter withdrawal time.
