• Description:
  Strain-softening behavior of rock and coal layers around a coal mine opening was simulated using a quasi-elastic approach, which accounts for residual strength after failure. This simulation was achieved in such a way that material values were modified after each run, according to stress distribution, until the simulation reached an equilibrium condition, MSC/NASTRAN Finite Element Method program was used for the simulation. The effect of a yield pillar system was analyzed in comparison with a regular pillar system. The results agreed with the field measurement in terms of stress distribution and floor heave.
