Rockfalls are one of the hazards that may be associated with open pit mining. The majority of rockfalls occur due to the existing conditions of slopes, such as back break, fractures and joints. Constructing a berm on the catchbench is a popular method for the mitigation of rockfall hazards in open pit *** width of the catchbench and the height of the berm play a major role in the open pit bench ***, there is no systematic method currently available to optimize the size of these parameters. This study proposes a novel methodology which calculates the optimum catchbenchwidth by integrating the rockfall simulationmodel and geneticalgorithm into a simulation-optimizationmodel. The proposed methodology is useful when used to determine the minimum catchbenchwidth, or the maximum overall slope angle, insuring that a sufficient factor of safety of the slope is included while maximizing the overall profitability of the open pit mine.
