摘要
什林煤业10-102回采工作面在过构造带期间由于推进缓慢,导致出现CO浓度超限,针对该工作面的实际情况,对工作面CO浓度超限原因进行分析,结合矿井现有设备及各种防灭火技术的特点,采取施工密闭、注氮等方法,降低采空区氧浓度及消除高温点,消除火灾隐患,保证了工作面的安全生产。
Due to crossing the structural zone which caused the slower advancing in No. 10-102 working face in Shilin Coal Mine, the concentration of CO is far beyond the standard. In view of the actual situation of the working face, the paper analyzes the causes of CO problem, combined with the onsite conditions and a variety of fire fighting technology, sealing and nitrogen injection methods are applied to cut down the oxygen concentration in goaf, to lower the temperature, thus the hidden risk of fire eliminated, safety production ensured.
