Abstract: To investigate the impact instability of the roadway support system caused by the collapse of the overlying hard roof strata during the coal mining process, and to guide the prevention and control of mine rock burst disasters, taking I010203 working face of Kuangou Coal Mine as the background, Abaqus numerical analysis software was used and a refined model was established to simulate and analyze the support system of the hard roof roadway under the combined action of dynamic and static loads, the propagation process of dynamic loads, as well as the dynamic response characteristics of roadway surrounding rock under the combined action of dynamic and static loads, are also analyzed. The anti-impact capacity was evaluated on the basis of checking the anti-impact capacity of the roadway support system. The results show that the current support system can effectively resist the impact loads generated by previous large-energy events.
