Design of wireless monitoring system for coal spontaneous combustion in goafs

Coal spontaneous combustion in the goaf is one of the major disasters.Monitor of coal spontaneous combustion in the goaf plays a vital role in constitution of fire prevention and control measures.In view of disadvantages of parameter sampling in the goaf,a wireless monitoring system for coal spontaneous combustion in the goaf was designed on the basis of original base station and central station in mines.The system was composed of signal emitters in the goaf and handheld receiver in the tunneling face.It realized the real-time monitor of the goaf parameters via underground monitor network.
