高瓦斯工作面的瓦斯抽放技术

Gas Drainage Technique for Highly Gassy Coal Faces

介绍了我国两个典型邻近层瓦斯抽放矿井(阳泉局及松藻局)提高瓦斯抽放率的方法。阳泉局采用顶板岩巷抽放法,松藻局采用针对瓦斯源的综合抽放方法。这两种方法在各自的条件下都取得了好的瓦斯抽放效果。

The paper presented the methods for improving gas drainage rate which are used in two typical mines (Yangquan Coal Mining Administration and Songzao Coal Mining Administration) exercising gas drainage from adjacent seams. Gas drainage from roadway in roof rock is used in Yangquan Coal Mining Administration and comprehensive gas drainage based on gas source is used in Songzao Coal Mining Administration. Good effectiveness was obtained for two drainage methods under its own conditions.
