Application Summary AI generated

This standard specifies the classification criteria and laboratory testing procedures for evaluating the bursting liability of coal-rock combination samples. It is applied in the mining industry, particularly for assessing rock burst risks in underground coal mines during mine design, excavation, and support planning. The standard provides a systematic method to classify the propensity of coal-rock combinations to dynamic failures, aiding in hazard prevention and control.
