Abstract To explore the acoustic emission characteristics of limestone with different rockburst tendencies and its damage model，the laboratory tests on the rockburst tendency of limestone with different burial depths were conducted. The rockburst tendency of limestone which was collected in the same borehole burial depth from 600 to 1 000m was identified by integrating the elastic energy index WET criterion，the deformation brittleness coefficient Kε criterion and the linear elastic energy We criterion. The relationship between the accumulated energy of acoustic emission and the axial strain was derived using time as an intermediate variable. Based on the basic principles of damage mechanics，a damage model was established by the accumulated energy of acoustic emission. The result is that the rockburst tendency of limestone increases step by step with increasing the buried depth gradient. Before the peak stress，the number of acoustic emission events and the cumulative energy of limestone increase sharply，and the cumulative energy of acoustic emission evolves in the form of a “step” pattern. Rockburst tendency shows from none to intense，the lower the frequency of the high number of acoustic emission events，the longer the quiet period experienced by the accumulated energy，and the narrower the width of the “step”. The dissipation mode of the energy stored in the limestone gradually shiftes from the phased dissipation to the instantaneous release. The cumulative energy of acoustic emission of limestone without rockburst tendency increases with a power function，and the cumulative energy of acoustic emission of limestone with rockburst tendency increases abruptly in stages. The resulting damage model can be divided into two different forms based on whether the lime stone has a rockburst tendency. The three parameters A，BT and C in the damage model represent the energy storage capacity，the time of the energy release and the rate of energy release，respectively. The research provides theoretical reference for the discrimination of rockburst tendency.
