Abstract

In this paper, a new prediction method of rockburst in underground engineering has been proposed based on elastic energy index through cyclic loading and unloading test. The calculation formula has been explicitly explained and WET was gained through cyclic loading and unloading test result. Finally, we obtain the conclusion that skarn is a kind of hard brittle rock which has high rock burst tendency. In the cyclic loading and unloading test, the curve behaviors as a “n” shapke which indicate that its energy storage capacity increase first with cycle times and decrease after reaching peak point.
