煤矿井下火灾的自动探测与灭火技术方案的研究

Research on the Automatic Fire Detection and Fire Suppression Technique Scheme in the Coal Mine

摘要: 介绍了以基于拉曼散射的分布式光纤温度传感器对煤矿井下火灾进行自动探测的设计，分析了分布式光纤应用于煤矿井下的可行性和优越性，并结合水喷雾技术，共同构成煤矿井下火灾的自动探测及灭火系统。在发生非电气类火灾时，可以用其进行灭火，在平时可以用其对井下进行洒水除尘处理，实现资源的最大化利用。

Abstract: This paper introduced the distributed optical fiber temperature sensor based on Raman scattering for design of automatic fire detection in the underground coal mine. Feasibility and superiority of the distributed optical fiber applied in coal mine was analyzed. Combined with water spray technology, the distributed optical fiber constituted the automatic fire detection and fire extin-guishing system in the underground coal mine. In the event of non-electrical fire, it can be used to put out the fire, and be usually used for underground sprinkling service, which maximizes the use of resources.
