Abstract

As a kind of common and very serious natural disasters, rock burst was greatly caused by large mining depth and geological structures. Based on the experimental study of dynamic damage time, elastic energy index, rock burst energy index of complex structure coal in deep well, the burst tendency results were obtained. Comprehensive index method was applied in rock burst hazard evaluation on conditions of specific geological and mining technology as a foundation of monitoring and management in rock burst.
