To improve the safety level of belt conveyors, it was proposed to use heat detectors: optical fiber heat detectors were installed along the conveyor to detect temperature abnormality and locate the fire position; sprinkling units were then activated corresponding to the fire locations, to prevent any conveyor induced fire from deteriorating. The article also elaborates on the working principles, composition, and field application of the heat-detector-based fire protection system. The study serves as a reference for the fire protection of other mine transport systems.
