If the air leakage passage is connected with a fire area, the very serious results will be brought about. The air leakage of the 9211 airway in the Beizu mine shaft is measured by using the method of the continuous and quantitative releasing of SF₆, and the air flow leaking into the 9211 air way can quantitatively determined. The amount of the air leakage is calculated by determining the shortest distance of the detection, the detection time, the release volume and other air leakage determination parameters, according to the change of the concentration of SF₆ gas. Two air leakage areas in the 9211 air way are detected, to provide a foundation to take corresponding measures of prevention and control of the mine air leakage, and the technical support to the mine fire prevention., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null,

风巷。通过确定最短采样距离、采样时间及SF₆释放量等漏风测定参数，定量计算了漏入风量及漏风率的大小，结合SF₆气体浓度的变化，确定9211 风巷巷道内有两处漏风区域，进而为采取针对性的防治矿井漏风措施提供判断依据，同时为该矿火灾防治提供技术支持。, correspAuthors=null, authorNote=于树江，博士研究生，研究方向为煤矿安全，电子信箱：2322155130@qq.com,
