Advantages of optical fiber sensor applications in the mine safety monitoring system were introduced. The operational principle of optical fiber sensors developed for mine applications were described, which included laser spectral analysis based gas sensors, fiber Bragg grating based physical sensors and distributed optical fiber temperature sensor. Meanwhile, typical applications of optical fiber sensors in mine safety Internet of things were introduced including laser methane sensor in coal mine safety monitoring system, optical fiber acceleration sensor in micro-seismic monitoring system and distributed optical fiber temperature sensor in goaf fire monitoring and pre-alarming system.
