摘要：
Highlights The radius of the plastic zone and the radial stress is introduces into the stress-intensity ratio. A new rockburst criterion is proposed to predict the rockburst classification. The certain relationship between the rockburst rating and the radius of the plastic zone and radial stress is studied.
