Roof failure evolves through stress redistribution and plastic softening, forming a 3.5 m plastic failure zone.
Field application of the graded anchor composite support technology leads to a 73.3% reduction in roof subsidence.
The study utilizes numerical simulations and field monitoring to address support system deficiencies in roadways.
Engineering guidance is provided for improving roadway support in weakly cemented geological conditions.
