Sensitivity and Probabilistic Analysis

Perform probabilistic analysis to determine the probability of failure and model variability in key parameters by assigning statistical distributions. Conduct sensitivity analysis using a range of values to evaluate the effects of changing model parameters on the factor of safety.

Empirical Design Method

Originally developed for steeply dipping ore body geometries, you can apply the most appropriate empirical relationships to your model by estimating crown geometry and assessing the stope geometry as steep or shallow.

CPillar Across Applications

  • Mining
  • Excavations
  • Roof Pillars

Mining

Assess the risk of crown pillar failures using probabilistic analysis, essential for underground mine closure planning and decommissioning.

CPillar Mining Applications

Excavations

Analyze the stability of surface crown pillars under gravitational loading, while considering shear strength, lateral stress, and water pressure effects acting at the abutments.

CPillar for Excavations

Roof Pillars

Determine the maximum roof span using rigid, Voussoir, elastic, or empirical methods.

Cpillar for Roof Pillar Applications

The Latest Features

  • Polygonal Pillar Geometry

    Conduct rigid analysis (plug failure) on custom polygonal-shaped pillars of uniform thickness with optional non-vertical pillar abutments.

  • Locked-In Stress

    Define locked-in stress, and principle lateral stresses to model in-situ stress conditions. The 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.

  • New Plate Bending Analysis Formulation for Elastic Analysis

    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.
