The Northwestern University Rigid Block Model (NURBM) has been extended to explicitly model dilatant behavior of rock joints. By incorporating dilatancy, the resistance to shear displacement and slip is provided by contact roughness as well as frictional resistance. Increasing joint roughness increases cavern stability by interlocking of adjacent blocks.
