Abstract In view of the complexity of the formation mechanism of rockbursts and the problem that it is difficult to prevent the occurrence of rockbursts accurately and effectively，rock mechanics experiments of rock samples with a filled cavity were performed to analyze the energy evolution mechanism and failure mode of the rock samples under different filling conditions and to reveal the energy regulation evolution mechanism of the hole filling of the rock samples with strong impact tendency. The results show that compared with undrilled intact rock samples，the mechanical parameters of rock samples with an unfilled，copper tube-filled(rigid filling) or solidified body-filled(flexible filling) borehole are deteriorated. The energy evolution law of the rock samples under different filling conditions is roughly the same as that of the intact rock samples except for in the yield failure and failure stages. Due to the existence of boreholes，the initial damage of the rock samples is aggravated. Filling cooper pipe increases the total strain energy absorbed by the rock samples，while filling consolidation body not only improves the strength of the rock samples but also changes the strong and brittle characteristics of the rock samples. The filling modified energy conversion efficiency was constructed，and the energy regulation mechanism of“first release + then absorption”was further explained by calculating the energy conversion efficiency. Finally，the sequence of impact tendency of the rock samples under different filling conditions was compared and analyzed，and it was found that drilling filling copper pipe and solidified body can better reduce the degree of rock burst and the latter is better than the former. However，it is necessary to pay attention to strain increase behavior under the solidified body-filled condition，which possibly results in disasters under large deformation environment.
