摘要
随着我国煤矿采掘机械化和电气化程度的提高,矿井火灾越来越成为煤矿的重大灾害之一。采用分布式光纤感温报警系统,能实时测量到井下巷道中铺设的光缆沿线长期工作的温度变化情况,一旦实时监测的温度与平时测量积累的温度经验值不同,系统就可做出合理判断。重点介绍系统构成及原理,系统监测软件和技术关键。该系统经现场实际应用,取得了较好的效果,它可对火灾进行预测和辅助处理,对井下事故发展情况进行掌控。
With the improvement of mining mechanical and electrification in domestic China, the mine fire hazard has become one of the serious disaster. The distributed fiber temperature alarm system is adopted, which can real time measure the temperature change of fiber in long time work condition at underground tunnel. Once the real time monitoring of the temperature is different with usual accumulated temperature level, the system can judge reasonable. Introduces the systems＇ structure, principle and monitoring software. This system gains good effect by application, which can predict fire and makes some auxiliary treatment, control the development situation of underground mine accidents.
