Abstract

: Design, selection and performance prediction of excavators are very delicate for project planning and cost estimation in mechanical mining and mechanized tunneling. Rock cuttability assessment in mechanized excavation includes investigation of rock mechanical behavior and rock-cutting tool interaction. Use of laboratory scale Rock cutting tests is the most reliable method for accurate assessment of rock-tool interactive behavior in a situation close to its actual field condition. In this study, small scale linear cutting test was used for evaluating the rock cuttability and its relationship with rock mechanical parameters. To perform this action, rock samples of Upper-red sandstone were prepared for rock physical and mechanical characterization tests. The results obtained from cutting tests revealed that the cutting depth has a direct linear and a non-linear relationship with the cutting force, and the specific energy, respectively. Also, the cutting velocity showed no significant relationship with cutting force and specific energy. Moreover, the cutting forces obtained from the experiments showed a good agreement with those obtained from the theoretical model developed by Evans. However, these results are preliminary and need to be further verified with much larger cutting tests on various rock specimens.
