Abstract：Based on the experimental data，the data of bursting liability of coal and rock are analyzed. According to the problems existing in the industry standard of bursting liability of coal and rock，the uniaxial compressive strength(UCS) of coal selecting as a new index to evaluate the bursting liability of coal is put forward，and the criterion is also involved. The applicability of previous bursting liability index of roof rocks is analyzed. The new formula and its new index and criterion for bursting liability of roof rocks are deduced based on the freely supported beam model. The relationships between the brittleness index，moisture content，etc. and the bursting liability are analyzed. The results show that the UCS of coal can be used as the index to evaluate the bursting liability of coal. The calculated results of bending energy index based on the freely supported beam model are consistent with actual condition.
