Abstract:

Percussive and rotary drills are widely used in engineering projects such as mining and construction. The prediction of penetration rates of drills by indirect methods is particularly useful for feasibility studies. In this study, raw data obtained from the experimental works of different researchers were used to establish the new statistical models for estimating the penetration rate of percussive and rotary drills from brittleness indexes, B1, B2, and B3. For this, correlation between the penetration rate percussive and rotary drills with brittleness indexes statistically was investigated using multiple regression analyses. In these analyses, the penetration rate of percussive and rotary drills were considered to be the dependent variable, which is dependent on the independent variables of the brittleness indexes. The validity of the predictive models was validated by statistical tests. The results showed that statistical models are in good accuracy for estimating the penetration rate of percussive and rotary drills.
