A New Rock Stress Factor for the Stability Graph Method

CIM Montreal 2011
Rory Hughes, Hani Mitri, Benny Zhang,
Abstract The modified stability graph method is a popular
tool which can provide an estimate of anticipated
stope stability. The rock stress factor is one of
the input parameters used in the modified
stability graph method and is a penalty factor
based on the mining-induced stress conditions
along the face under evaluation. The new rock
stress factor proposed by the Authors corrects a
deficiency in the method. The new rock stress
factor addresses the detrimental effects of a low-
stress regime and through a series of case studies
this paper will seek to illustrate the benefits of
this adjustment.
