Publication Date	1996
Personal Author	Beus, M. J.; Orr, T. J.; Whyatt, J. K.
Page Count	39
Abstract	This research was conducted in the No.10 Shaft in the Sunshine Mine in the Coeur d'Alene Mining District of nothern Idaho. Major tasks for this work included (1) definition of the deformation and loads acting on the rock mass and shaft support system, (2) determination of the physical properties and strengths of the rock mass, (3) definition of the geometry of the shaft and surrounding mine openings, (4) simulation of the geometry and removal of the rock mass, and (5) definition, analysis, and validation of structural behavior at the scale of interest.
