高瓦斯矿井综采工作面带采隅角瓦斯治理与研究

Treatment and Research of High Gas Mine Fully Mechanized Working Face Corner Gas

21111工作面是东庞矿11采区第11个综采工作面,由于工作面地质条件因素,该工作面切眼布置,需要在工作面向前推进时带采5 m,在轨道回风巷造成工作面隅角,瓦斯积聚加大,影响工作面正常生产,通过瓦斯治理技术,采取措施,有效地解决了综采工作面带采上隅角瓦斯超限问题,保证了该工作面的安全顺利回采。

21111 working face was the eleventh fully mechanized working face of No.11 mining area in Dongpang Mine,due to geological conditions factors of working face, the cut eye arrangement in the working face needed with mining 5 m,with working face corner in return airway and increasing gas, which affected the normal production of working face, through the gas control technology, effectively solved fully mechanized working face with mining upper corner gas overrun problem with measures, which ensured the safe recovery of the working face.
