AI Technical Summary
The existing design of anchor bolt support parameters lacks guidance on energy angle, resulting in deviations between the design parameters and the actual support scenarios, and making it impossible to effectively control rockburst disasters in deep mines.
By conducting dynamic tests on support anchor bolts to obtain their dynamic energy absorption capacity, establishing an overall rock stratum model to simulate excavation, calculating the elastic strain energy that can be released per unit volume of surrounding rock, determining the number of anchor bolts required per row length in the roadway, evaluating the anchoring effect through field tests, and optimizing the anchoring parameters by combining theoretical calculations, numerical simulations, and actual verification.
This improved the accuracy of anchoring parameter design in rockburst hazard areas, reduced the risk of dynamic disasters in mines, and ensured construction safety.
