CPillar across Applications
Assess the risk of crown pillar failures using probabilistic analysis, as part of underground mine closure planning and decommissioning.
Analyze the stability of surface crown pillars under gravitational loading, while taking into account shear strength, lateral stress, and water pressure effects acting at the abutments.
Determine the maximum roof span using Rigid, Voussoir, Elastic, or Empirical methods.

- Polygonal Pillar Geometry
- Locked-In Stress
- New Plate Bending Analysis Formulation for Elastic Analysis
Conduct Rigid Analysis (plug failure) on custom polygonal-shaped pillars of uniform thickness with optional non-vertical pillar abutments.
Define locked-in stress, and principle lateral stresses to model in-situ stress conditions. Locked in stress option is available when using Gravity lateral stress type to set the lateral stress at the pillar surface to a non-zero value.
Analyze two-way plate bending of rectangular plates with clamped-edge boundary conditions, following the method from Theory of Plates and Shells (Timoshenko, 1969). Considers Elastic Buckling failure mode due to bending, and factored shear failure along the abutments.
