摘　　要：根据矿井回采过程中各源瓦斯涌出规律特征,对采煤工作面瓦斯涌出进行分源。基于采煤工作面实时瓦斯浓度观测曲线和观测数据及其中隐含的生产条件信息,提出采面煤壁分源预测方法,并对古汉山矿14171工作面进行现场参数提取分析,得出该工作面煤壁瓦斯体积分数与时间变化规律及两者变化公式。According division gas source emission characters during coal mining, and then gas emission sources of coal cutting workingface was distinguished, based on real time methane density observation curve of coal cutting working face and observation data and pro-duction situation information, working face coal wall division source forecast method was put forward, and then the site parameters of14171 working face of Guhanshan coal mine was collected and analysis, the variation law between working face coal wall methane vol-ume fraction and time and variation formula of two were obtained.
