Many open-cast mines in Algeria are regularly affected by instabilities that disrupt the exploitation activity, such as Chouf Amar's career where recurrent failures are caused by the combined action of a number of predisposition and triggering factors. I this study we uses a commbined-Geomechanical, Kinematical, numerical and limit equilibrium analysis to evaluate the behaviour of the discontinuous rock masses in open pit mine, and we chooses the Chouf Amar career as a case study. We determines nine main sets of discontinuities in the three main facies of the stone-pit. We proved also that the quarry suffers from various types of failures and that blasting declines the values of safety factor. We find out the causes of the 2009 slip-incident. By this combined approaches we have made it possible to optimize operations and to improve career productivity while ensuring the safety of equipment and personnel.
