The "goaf fiber temperature monitoring system" is to lay high-strength armored fiber into the goaf with the moving of the working face, and use the temperature characteristics of the laser itself conducted in the fiber to conduct the temperature information to the ground host, so as to obtain the temperature information in the goaf, to avoid the spontaneous combustion of the goaf fire to produce a lot of heat and carbon monoxide, resulting in underground production and personnel safety risks.
