Optical frequency domain reflectometry response mechanism of overburden movement and fracture evolution under repeated mining of closely spaced double coal seams

At present, Optical Frequency Domain Reflectometry (OFDR) technology has made certain progress in multi-seam stress monitoring, but few studies have applied OFDR to investigate the dynamic evolution of overburden fractures under repeated mining of closely spaced double coal seams. Taking the 360608...
