| 摘 要： | 以长期停产的综采工作面为例，介绍了通风系统调整、封堵漏风通道、采空区蓄水、喷洒阻化剂及注氮防灭火等综合防灭火技术管理手段。以综采工作面架间温度、采空区温度，工作面架间CO，采空区、工作面回风巷CO及自然发火标志性气体为监测对象，经现场试验，综采工作面采空区及回风隅角CO浓度显著降低，综采工作面采空区温度显著降低。通过综合防灭火措施的有效实施，破坏了采空区遗煤自然发火所需的蓄热条件，杜绝了采空区自然发火隐患，取得了良好的防灭火效果，保证了综采工作面在停产期间的安全，为工作面后期正常安全回采创造了有利条件。

| Abstract: | Taking the long-term shutdown of fully-mechanized mining face as an example，this paper introduced the comprehensive fire prevention and extinguishing technology management means，such as ventilation system adjustment，blocking air leakage passage，goaf water storage，spraying chemical inhibitor and nitrogen injection fire prevention and extinguishing.Based on the monitoring object of the temperature between the supports，goaf，CO between the supports，CO in goaf，return air roadway and spontaneous combustion marker gas in fully-mechanized mining face，the CO concentration in goaf and return air corner of fully-mechanized mining face was significantly reduced，and the temperature in goaf of fully-mechanized mining face was significantly reduced.Through the effective implementation of comprehensive fire prevention and extinguishing measures，the thermal storage conditions required for spontaneous combustion of residual coal in goaf were destroyed，the hidden danger of spontaneous combustion in goaf was eliminated，good fire prevention and extinguishing effect was achieved，the safety of fully-mechanized mining face during shutdown period was guaranteed，and favorable conditions were created for normal and safe mining in later period of working face. |
