摘要
由于综放工作面开采强度大，引起瓦斯涌出量成倍增加，严重制约着工作面的安全生产．针对瓦斯涌出强度大的问题，通过在山西潞安矿务局漳村煤矿综放工作面布置测点、测线，进行现场观测和研究，分析论述了工作面设置排放瓦斯巷解决瓦斯严重超限问题时，综放工作面的瓦斯分布状况及涌出特征．
The safety production at working face have been seriously restricted because of the enlargement of the mining intensity which causes the gas emission rate increases doubly in a sublevel caving mine face.In order to solve the above problem,some field observation and research have performed at Zhangcun coal mine of Lu′an,Shanxi province,which enable to analyse and explain the feature of gas distribution and gas emission when a gastunnel is set up to deal with the serious gas emission beyond the limit.
