Recent advances in Distributed Optical Fiber Sensing (DOFS) technologies, particularly Brillouin Optical Time Domain Analysis (BOTDA) and Rayleigh Optical Frequency Domain Reflectometry (ROTDR), have opened new pathways for real-time, high-resolution monitoring in mining. The methodology involves embedding the sensing fiber into boreholes within the overlying strata and employing grouting to achieve effective coupling with the rock mass, a critical step that restores the in situ geological environment and ensures measurement reliability. Precise monitoring and early warning of these factors are essential for disaster prevention and control. A critical aspect of this management is ground control, focusing on addressing rock instabilities that arise from the mining processes and ore removal.
