Research on Real-Time Dynamic Monitoring System of Fiber Grating in Coal Mine Bolt Roof Support Roadway
Abstract：The real-time, dynamic monitoring system of coal mine bolt support roadway is made up of fiber grating sensors. Based on fiber grating FBG sensor principle, the sensor can realize the measurement of physical quantity such as straining, pressure, temperature, displacement and vibrating etc. through light wave information. The sensor has the advantages of anti-electromagnetic interfere, passive intrinsically safe, long distance transmission and series and parallel connection. After operation, this monitoring system gains good effect through underground coal mine industrial test.
