摘　　要：以神东矿区补连塔煤矿12煤四盘区综采工作面回风隅角低氧防治为案例,对浅埋深近距离煤层群开采的同一盘区大采高综采工作面回风隅角出现的"低氧"与"未发生低氧"2种现象进行原因剖析,并通过通风系统调整、回风隅角管理、开采设计、巷道一般防火密闭设计、地表回填等多项技术多措并举,成功地解决了综采工作面回风隅角低氧问题,确保了矿井的安全、高效生产。A case study was made on the prevention and control of low oxygen in return airway corner of fully-mechanized working face of 12 coal No.4 panel in Shendong Mining Area Bulianta Coal Mine, we analyze the reasons of ＂low oxygen＂ and ＂without low oxygen＂ in return airway corner in shallow buried depth close coal seam group mining in the same area with large mining face. Through ventilation system adjustment, return wind corner management, mining design, general fire seal design in roadway, surface backfilling and other technologies and multiple measures to successfully solve the problem of low oxygen in the return airway corner of fully mechanized working face and ensure the safe and efficient production of mine.
