The coal-burst tendency judgment standard.

Name		Burst tendency test indexes
		Computing model
Burst tendency judgment standard	No burst tendency
	Weak burst tendency
	Strong burst tendency

Note: D_T is the dynamic failure time; W_ET is the elastic energy index; K_E is the burst energy index; R_C is the uniaxial compressive strength.
