Özet
In this study, the effects of physical and mechanical properties of the rocks on the performance of impact hammers used to crush boulders in muck piles produced after drilling and blasting were investigated for seven different quarries operating in Ni?de province. For this purpose, the muck piles were analysed using image processing method to determine the amount of the boulders. Total operating time and breaking rate of the hydraulic impact hammers were measured during a secondary breaking task for oversized boulders. Hydraulic hammers with the similar specifications were employed in all quarries visited in this study. In this regard, it was possible to investigate the relationships between hydraulic hammers' instantaneous production rate with the physical and mechanical properties of the rocks by simple regression method. Accordingly, significant linear relationships in various levels were found between the physical-mechanical properties of the rocks and hydraulic hammer performance. At the end of the study, a multiple linear regression equation was proposed to estimate instantaneous production rate of the impact hammers based on the independent parameters. © 2020 Union of Chambers of Engineers and Architects of Turkey.
