| 摘 要： | 高位“E”巷是在综采工作面风巷内错5m顶板施工一条专用排瓦斯巷。通过高位“E”巷在采空区内部形成低负压通道,改变瓦斯的移动方向,消除了上隅角瓦斯积聚,降低采面回风流瓦斯浓度,保证回采工作面的安全回采。

| Abstract: | A high level "E" gateway is a special gas drainage gateway excavated 5 m aside and above the roof of the fully mechanized coal mining face.With the high level "E" gateway,there would be a low negative pressure channel in the goaf,which would change the moving direction of the gas and eliminate the gas concentration in the top corner of the mining face.Also the "E" gatway would reduce the gas content in the air return way and could ensure the safety mining operation of the coal mining face. |

| Keywords: | high level "E" gateway fully mechanized coal mining face gas prevention and control |
