Mechanical Properties and Damage Behavior of Rock-Coal-Rock Combined Samples under Coupled Static and Dynamic Loads

Table 1

Burst tendency index of the 3-3# coal seam and siltstone from Yutian coal mine.

Coal burst tendency index
Dynamic failure duration (ms)	Elastic strain energy index	Bursting energy index	Uniaxial compressive strength (MPa)	Burst tendency classification
37.60	3.44	20.79	17.82	Strong
Siltstone burst tendency index
Elastic modulus (GPa)		Bending energy index		Strong
12.20		169.88
