摘　　要：综掘工作面双巷采用绕掘的掘进方式,通过在底抽巷施工穿层钻孔、工作面打短孔预抽工作面瓦斯、在横川施工本煤层钻孔抽放瓦斯等措施解决了综掘工作面瓦斯问题。The double roadway of the comprehensive excavation working face adopts a surrounding excavation method,which solves the gas problem in the comprehensive excavation working face by drilling through layers in the bottom extraction roadway,drilling short holes in the working face to pre-extract gas,and drilling holes in the coal seam of Hengchuan construction to extract gas.
