    Reason Analysis and Prevention Technology of Low Oxygen Concentration in Return Airway Corner of 22613 Working Face in Daliuta Coal Mine

    • 摘要: 针对大柳塔煤矿22613工作面回风隅角低氧防治难题,从低氧气体的来源、低氧气体的涌出原因、大气压力变化等方面入手对回风隅角O2浓度降低原因进行分析,研究采取采空区封堵漏风、邻近采空区卸压、局部通风机抽排和加强监测监控等综合防治技术措施确保回风隅角O2浓度处于正常水平,实现矿井安全、高效生产。

       

      Abstract: Aimed at the prevention and control problem of low oxygen in the return airway corner of 22613 working face in Daliuta Coal Mine, starting from the sources of low oxygen gas, the emission of low oxygen gas, the change of atmospheric pressure, the reasons of low hydrogen concentration in return airway corner are analyzed. By taking integrated control technique measures such as sealing air leakage of mined out areas, reducing the air pressure of neighboring mined out areas, installation of local fans and strengthening the monitoring to control the oxygen concentration at normal levels and guarantee mine safe and efficient production.
