Abstract: In view of the serious impact deformation and damage of the hard and thick roof roadway surrounding rock in the syncline structure area, we adopt theoretical analysis, numerical simulation, and on-site measurement methods to study the impact damage mechanism of the hard and thick roof roadway in the syncline structure area.A collaborative anti-impact control measure for the unsupport of roadway surrounding rock, effectively improving the stability of the roadway surrounding rock.Research has shown that there is a concentrated area of compressive stress in the hard and thick roof of the syncline structure, forming a seismic source layer for mine impact.There is a high static stress concentration zone of 23.95～41.16 MPa within a range of 3～6 m in the synclinal axis roadway, and the impact damage of the roadway is severe due to the superposition of static and dynamic stress.The shallow cracks in the surrounding rock of the synclinal axis roadway are developed, and the anchoring performance of anchor rods is poor.The dynamic load and impact resistance performance of the roof anchor cables are poor, which is prone to certain damage.By adopting the collaborative anti-impact control technology of full section pressure relief and deep anchor reinforcement, the stress and dynamic load stress wave transmission path of the surrounding rock of the roadway are cut off, improving the anchoring and anti-impact performance of the surrounding rock of the roadway.The deformation of the surrounding rock of the roadway is reduced by 63.57% to 65.90%,and high-energy microseismic events are reduced, while small energy microseismic events are increased, enhancing the stability of the surrounding rock of the roadway.
