Abstract: Aim at the current existing problems of mine used sensors in coal mine safety monitoring system, such as low accuracy、 poor stability、 low reliability、 easy to be electromagnetic interfered and so on , a novel fiberoptic sensing technology is proposed for coal mine industry. Several kinds of application projects of fiber pressure sensing technology in coal mine are emphatically discussed, such as pressure and stress check like coal mine trucks weighing, bolt stress, water level and so on. The results indicate that due to intrinsically safe、 corrosion resistance、 high sensitivity、 long life, the fiber sensing is widely suitable for the environmental parameters detection of coal mine production, and it provides the innovative idea and practical solution for coal mine safety monitoring system.
