Rockburst Prediction of a Cut and Fill Mine by using Energy Balance and Induced Stress

Rockbursts have been the major hazard in deep hard rock mines,especially at an overhand cut and fill mine. It is caused a comprehensive prediction in accordance with strain energy issue. This study has been carried out by experiment to calculate the property of strain energy stored in rocks and by using numerical modeling to compute energy release rate (ERR), energy storag e rate (ESR) and burst potential index as components of energy balance. Empirical analysis by using Q system is also done to see the ratio of σ1/σc to predict rockburst.
