A Cascading Pillar Failure can occur in certain room-and-pillar mines when one pillar in a mine layout fails which transfers its load to neighboring pillars causing them to fail, and so forth. Whether failure occurs in a stable, nonviolent manner or in an unstable violent manner is governed by the local mine stiffness stability criterion. To apply this stability criterion, a boundary-element-method computer program with a strain-softening material model calculates the local mine stiffness and the post-failure pillar stiffness. The behavior of computer simulations changes depending on whether the model satisfies or violates this stability criterion. Example analyses illustrate how the computer program can simulate stable and unstable failu...
