Abstract
 Bench stability in mines is an important element of pit design. There is
no consensus on which criteria to use to evaluate the bench design reliability.
When designing the pits, bench design reliability is analyzed according to one
or two criteria. The objective of this paper is to analyze the bench design for
the Tiriganiaq pit, part of the Meliadine mine project, with regards to the
reliability criteria found in the literature and in practice. The paper presents
the similarities and the differences between the results obtained according to
the various criteria and it proposes a systematic multicriteria approach to
evaluate pit bench design reliability using susceptibility maps.
