- •
We model bedding plane slip to predict the spatial distribution of thrust faults.
- •
We find that slip along bedding contact surfaces perturbs the local stress field.
- •
Strain energy density and Coulomb stress are calculated as failure indicators.
- •
Simulations predict increased propensity for failure where thrust faults are found.
- •
This modeling approach may help predict hazardous roof conditions in mines.
