Application of KJ711 Distributed Fiber Optic Temperature Measurement System in Coal Mine

The article introduced the principle of distributed fiber optic temperature measurement base on Raman scattering. The KJ711 distributed fiber temperature measurement system for mine was used to achieve the real time on-line monitoring of the surface temperature of the power cable and the environmental temperature of the roadway, according to the distribution characteristics of power cables under No. 4 Coal Mine of Pingmei Shares.
