Abstract: In this study, the AHP and Expert choice software were used for data analysis. The criteria to be used for selecting agents were determined and then scorings were done with authorized engineers. Results indicated that the priorities of the various demolition agents in the case of laminated schist stone was hydraulic hammer>expansive chemicals>dynamite>CARDOX>rock cracker and for dry sandstone, limestone, marl was rock cracker>CARDOX>expansive chemicals>dynamite>hydraulic hammer. Also, the alternatives were arranged as rock cracker>CARDOX>dynamite>hydraulic hammer>expansive chemicals for moist sandstone, limestone and marl. To conclude, this study reveals that decision-making methods can be used in the process of selecting demolition agent for the rock breaking.
