Petrography of included rock samples was also conducted for the computation of geotechnical wear indices including Schimazek’s F-value, rock abrasivity index and the Vickers hardness number for rocks. Initially univariate regression analysis was performed to check the dependence of drillability parameters on physico-mechanical properties and rock wear indices. Significant correlations of drillability parameters with uniaxial compressive strength were found. Similarly, Sievers’ J-value and drilling rate index showed considerable dependence on Schimazek’s F-value.
