Belt conveyor is widely applied in the underground

  With the development of the coal industry, belt conveyors are widely used in the underground, but the conveyor belt fire accident has happened quite frequently, and some even

cause serious injury or death. Therefore, the analysis of Belt conveyor fire cause of the accident, and take appropriate safety precautions,

Belt conveyor on top anti-fire accidents particularly necessary.
       Belt conveyor belt fire causes much because of quality problems. Mine still use some non-flame-retardant or flame retardant poor belt. However, due to higher prices

retardant belts, especially coal enterprises to enter the market economy, the shortage of funds, poor non-flame retardant and flame retardant

The lack of timely replacement of the belt, and some manufacturers produce the best quality belts reach flame resistance requirements, which gave the conveyor belt fire

potential problems.
        Another aspect is the management of belt conveyors. Failure caused by belt conveyor belt conveyor belt fire due to the belt by the card, the belt and the roller friction

fire; roller, roller does not rotate or mechanical reasons prisoners slow speed, belts and rollers, idlers

Friction fire; belt conveyor hydraulic coupling injection can also cause belt conveyor fire. Inclined belt conveyor safety protection is not complete. According to Coal Mine

Safety Regulations: drum drive belt conveyor deviation must be equipped with anti-slip, anti pile of coal, anti-low-speed, anti-tear warranty

Protection and over-temperature sprinklers, smoke alarm device. But the scene is not complete or not these protections normal use, you can not effectively prevent accidents.
      Fire equipment is not complete or does not work and can not extinguish the fire source. According to rules of order: the main belt road dust every 50m must install two

pipes, each belt must be equipped with two fire extinguishers and a set number of retries sand box, but the scene is sometimes equipped with fire extinguishers missing or

invalid

Therefore, in the event of fire in the conveyor belt can not be extinguished. Open flames and ignite combustible materials due to the belt when the belt conveyor Road sparking

electrical equipment and shooting sparks, welding sparks and open flame ignition of flammable Road belt bracket, grease, oil and other combustible materials cotton, it can

Ignition belt.
      Eliminate the use of non-flame retardant belts and belt of poor performance. Belt manufacturers must adhere to the implementation of the new standard flame retardant belt,

where the quality of substandard products may not be manufactured. Coal users must purchase from the formal channels most qualified retardant quality belt, belt must Bu wells

prior

Subject to sampling stations for flame retardant belt Kam test, only after passing through the quality inspection before they go down the river. Mine has been used for a non-

flame retardant belts and belt poor, must complete replacement plan period, did not change, they must be installed for a variety of security protection, and

Take practical fire safety measures. In short, eliminating the use of underground belt and flame retardant properties of non-poor belt. Strictly implement the conveyor belt

inspection, repair, maintenance responsibility, identify problems and timely treatment to prevent sick for more than pallet conveyor. To complete with belt conveyor

Security protection, the implementation of staff regularly checked, not allowed to use flammable hydraulic coupling transmission media.
