The present study uses rock deformation measurements to validate and calibrate a geomechanical model of the experimental Lucky Friday underhand longwall (lful) stope on the 5,100-ft level of the Lucky Friday Mine, Mullan, Idaho. This model suggested that stress-related ground control problems would be encountered west of the stope where the vein makes a right-angle turn and then splits.
