摘要
本文针对虎龙沟矿5^(#)层81511综放工作面采空区内遗煤量大、自燃风险高等问题,通过束管监测采空区自燃征兆,并对采空区采取了注氮、喷洒阻化剂、灌浆等综合防灭火措施。现场监测结果表明:采取综合防灭火措施后,采面回采期间采空区无CO涌出,同时采空区内温度未出现异常,采面采空区防灭火取得显著成效。
Aiming at the problems of large amount of coal remaining in the goaf and high risk of spontaneous combustion at 5^(#) layer in 85511 fully mechanized caving face of Hulonggou Mine, the beam tube is used to monitor the signs of spontaneous combustion in the goaf, in addition, comprehensive fire-fighting measures such as nitrogen injection, spraying of inhibitors, and grouting have been adopted for the goaf. The on-site monitoring results show that there is no CO gushing out of the goaf during the mining, and the temperature in the goaf is normal, which ensures remarkable fire prevention and control.
