Abstract：Based on the analysis of the occurring characteristics of rock burst and the anti-impact mechanism of bolt-net-anchor support. The anti-impact abilities of support were calculated from the perspective of the energy-absorbing property of support and energy balance theory. Taking account of the location deviation，the reliability parameterfor anti-impact supporting design was introduced to the feasibility analysis of seismic reverse calculation for supporting，and the anti-impact energies of existing support calculated with the long-term data monitored by“SOS”seismic system were analyzed and compared with real energies of rock bursts in different. Results show that strong tremors will turn into rock bursts under certain conditions. The flexible property of bolt-net-anchor support can absorb most or part of dynamic energy passed on to the anchoring zone，maintain the integrity and stability of the anchoring surrounding rock，support the internal surrounding rocks of roadway，and prevent the further failure of the surrounding rocks. This is an important factor in effective control of rock-burst. The theoretical calculation results combined withhave good comparability with actual data of rock bursts and strong tremors. The calculated anti-impact energy of existing support of previous rock bursts all have turning points with the decrease of ，and the calculated result of the strong tremor also coincides with the reality. This shows that the seismic reverse calculation method combined withis feasible.
