In order to enhance the anti-impact displacement performance of the anti-impact support bracket to reduce the impact pressure hazard caused by deep coal mining, the numerical simulation of vertical compression of the existing pre-creased components was based on, the reaction force elevation and wall strain evolution were linked together, followed by the study of the changes in wall strain after setting ribs, embedded tubes, and circular collars, exploring the law of influence of different structural parameters on the energy absorption effect of the reinforced components, and then using the NSGA-Ⅱ genetic algorithm for optimization and solution, finally determining the optimal dimensions: rib thickness of 3.00 mm, embedded tube thickness of 2.45 mm, and circular collar thickness of 4.31 mm; furthermore, through the simulation and analysis of the results, it was found that: the optimized component is better than the original component in terms of anti-impact performance, with the peak value of the reaction force rising by 8.16%, the average counterforce increasing by 46.8%，the coefficient of load fluctuation dropping by 26.3%, the total energy absorption rising by 57.08%, and the energy absorption performance being better and the reaction force fluctuation being more stable. The research results can provide useful references for the design of anti-impact energy-absorbing components.
