Figure 5 After the open fire was discovered, fire extinguishing and sealing treatment began
on March 13. From the curve, the temperature of the front and rear end of the sealed optical
cable increased obviously. Especially after the first 200 meters and the back 800 meters.
5 CONCLUSION
Coal mine fire affects safe production. The use of distributed optical fiber temperature measurement technology has obvious advantages for coal natural ignition monitoring. The design
of intrinsically safe type further reduces power consumption and optimizes product reliability. Further promote the application of fire monitoring in coal external causes.
