Rockburst Is a Stress Ratio
The claim
Rockburst risk is set by the ratio of excavation-induced stress to rock strength rather than by depth.
01The mechanism
Bursting requires stress to exceed a fraction of strength; depth only raises stress where the stress state is unfavourable.
02Predictions
- P1Risk should track the ratio.
- P2Depth alone should mispredict.
03Refutation
Risk tracking depth would remove the stress ratio.
