Title: GROUND SUPPORT DESIGN TOOL
Abstract:
A method of designing an underground excavation may involve the steps of: Developing a plurality of input parameters for the underground excavation; performing a first design iteration to determine an initial ground support system design; evaluating a kinematic stability of the initial ground support system design; determining whether the kinematic stability meets a predetermined factor of safety; and reiterating the initial ground support system design until the kinematic stability meets the predetermined factor of safety.
