Mine conveyor belt fire warning system

Mine conveyor belt fire warning system

During operation, mine belt conveyors have fire hazards due to friction, electrical faults, etc. Therefore, distributed fiber optics are installed at the drive rollers, idlers, and other facilities prone to high temperatures on the belt conveyor to monitor the temperature of these key parts in real time. Once the temperature exceeds the preset threshold (e.g., 70℃-80℃, adjustable according to the actual situation), an alarm signal is immediately issued; at the same time, a smoke detector is installed every 20-30 meters along the route of the belt conveyor, and an infrared flame detector is installed at a suitable position above or around the belt conveyor to quickly detect the presence of smoke or flames.
