Abstract: The presence of intact rock bridges in the rock mass and their effect on the formation of step-path failure 
surface in pit slopes have been the subject of research in the last three decades beginning with the work of 
Jennings (1970). Step-path failure mechanism has been investigated more recently by rock mechanics 
engineers and consultants using advanced discontinuum numerical techniques. This paper reviews briefly 
the state of current application of step-path failure in practice and presents the results of one such 
investigation into the stability assessment of the northwest wall of A154 pit of Diavik Diamond Mine in 
Northwest Territories, Canada. Results of the numerical assessment are compared with those of limit 
equilibrium assessment and the importance of such investigations in practice, in particular in deep open pit 
mines where high stress conditions near the slope toe is present are discussed.
