摘　　要：为了解决突出煤层掘进时排放钻孔不能有效消除工作面瓦斯经常超限严重影响矿井生产这一难题,试验了水力挤出措施。分析实施该措施前后瓦斯涌出量、除尘效率及巷道掘进速度并结合对综合经济效益的计算,证明水力挤出措施是一项有效解决煤巷掘进工作面瓦斯超限的技术。In order to solve the serious production problem that the bleeder off hole can not effectively limit the frequent overrun of face gas when outstanding coal seam tunneling, the hydraulic extrusion measures were tested. Some aspects are analyzed, scuh as the gas emission dust efficiency and drivaging speed before and after implementing. Combining with composite economic results, hydraulic extrusion measures were demonstrated as an effective technique for the gas overrun of coal roadway excavation working face.
