Numerical Investigation of Relationship between Bursting Proneness and Mechanical Parameters of Coal

<div>Four indices obtained from the uniaxial compressive test and employed to classify the bursting proneness of coal: (a) uniaxial compressive strength (Rc); (b) elastic strain energy index (WET); (c) bursting energy index (KE); (d) duration of dynamic fracture (Dt).</div>
