201851 · In this evaluation, the drillability term was defined as a penetration rate. The rough estimations of the rock drillability may cause a great risk in terms of mining operations, selection of mining machineries and equipment and final price of the product. Also the total drilling cost can be estimated by the drilling rate equations.
