Description: This study was developed as part of an effort by the National Institute for Occupational Safety and Health (NIOSH) to better understand rock-mass behavior in longwall coal mines in highly stressed, bump-prone ground. The floor-heave and no-floor heave phenomena at a western U.S. coal mine cannot be properly simulated in numerical models using conventional shear-dominant failure criteria (i.e., Mohr-Coulomb or Hoek-Brown failure criterion). Kim and Larson (2019) demonstrated these phenomena using a user-defined model of the s-shaped brittle failure criterion in conjunction with a spalling process in FLAC3D.
