In the wake of the Crandall Canyon mine disaster, the National Institute for Occupational Safety and Health (NIOSH) revisited the issue of pillar design for deep cover retreat mining. Studies conducted at 30 mines added more than 200 new case histories to the Analysis of Retreat Mining Pillar Stability (ARMPS) database. Extensive statistical analyses were supplemented with numerical modeling using Boundary Element and Finite Difference techniques.
