Abstract: To solve the problem of hard roof rock burst in the multi-roadway intersection area of the 113₅₀ upper isolated island working face of Gaomei Company, through stress monitoring and numerical simulation, it is found that the stress concentration in this area is obvious, with vertical stress reaching −2.386 7×10⁷ Pa and horizontal stress reaching −3.789 4×10⁷ Pa, and the coefficient of stress concentration is 2.8-3.5. The fracture law of hard roof is systematically studied by utilizing microseismic monitoring and borehole television observation, its three-stage evolution mechanism of "initial fissure initiation-fissure propagation and convergence-breakthrough failure" is revealed. A prevention and control technology combining "interval control flushing" and "strong control flushing" is proposed, and a support system with "rigid-flexible coordination and graded yielding" is developed, including U36 type steel yielding bracket and TDM hydraulic yielding anchor rod, with a maximum yielding capacity of 450 mm, and a disaster monitoring and early warning system is established. The practice proves that this technology decreases the deformation rate of surrounding rock by 76.96%, reduces the frequency of high-energy events by 72.04%, significantly improves the safety of multi-roadway intersection areas and provides new ideas for rock burst prevention and control in deep coal mines.
