Abstract: The accumulation and release of energy in coal are closely linked to rock burst, with energy transfer being a key parameter for evaluating bursting liability. This study constructs an energy transfer model under energy source disturbance conditions, where we establish a relationship between impact energy index and elastic energy index, propose the proportion of energy φ, introduce the concept of energy transfer efficiency β based on an energy dissipation model during the transfer process, develop an evaluation method for bursting liability by multiplying two efficiency parameters η=βφ. We conducted experiments to identify bursting liability of 11 coal layers from 3 pairs of coal mines, whose reliability was verified by referencing results from 79 layered impact tendency identifications in other coal mines. Results show that 1)the proportion of energy release φ has boundary conditions with physical significance for ground pressure; 2)there is negative correlation between the efficiency β and Poisson's ratio which can model boundary conditions; 3)calculation results of the energy transfer index η show high consistency(88.61 %)with bursting liability identification results, reflecting the bursting liability of coal bodies. It can serve as a basis for evaluating "*" outcomes and is an effective indicator suitable for existing systems used to evaluate bursting liability.
