Abstract: Specific energy has been widely used to assess the rock cuttability for mechanical rock excavation. In mechanical rock excavation processes, engineers need to predict, of machine performance based on specific energy using easy applicable, more economical and simple sample preparation methods. In this study, P-wave velocity (Vp) and Schmidt hammer hardness (RL) tests are used as predictors for prediction of specific energy, which are thought to be a practical, simple and inexpensive test. For this purpose, rock cutting and Vp and RL tests were performed on 24 different rock samples. The Vp a nd R L values were correlated with specific energy values using simple and multiple regression analysis with SPSS 15.0. As a result of this evaluation, there is a strong relation between specific energy, Vp and RL values of rocks. According to the statistical analyses, specific energy values can be reliably predicted by using Vp and RL values of rocks based on laboratories studies. © 2019 Union of Chambers of Engineers and Architects of Turkey.
