摘　　要：为保证余吾煤业N1105工作面在掘进和回采期间能够保持高效安全生产,结合井下现场瓦斯地质条件,分别对工作面掘进以及回采期间采用邻近巷道区域预抽、迈步钻场边掘边抽、施工迎头释放孔、迎头钻孔预抽等措施及采用顺层钻孔采前预抽、切眼顶板释放孔、高抽巷抽采、钻场裂隙带抽采、采空区长立管埋管瓦斯抽采等措施,工作面实测煤层最大残余可解吸瓦斯含量为4.9920 m^(3)/t,满足工作面日产6001~8000 t瓦斯抽采达标要求。In order to ensure that the N1105 working face of Yuwu Coal Industry can maintain efficient and safe mining during the mining and recovery mining,combined with the underground gas geological conditions,measures such as Pre-drainage of bedding borehole before mining,release hole of open-hole cut roof,drainage of high drainage roadway,drainage of fractured zone in drilling field,gas drainage of buried pipe of long riser in goaf area were adopted,the maximum measured residual gas desorption content of coal seam in working face was 4.9920 m^(3)/t,which met the standard requireme-nt of gas drainage of working face daily output of 6001~8000 t.
