Research on Interdependence between Specific Rock Cutting Energy and Specific Drilling Energy

A method based on extensive laboratory and field measurements was developed to determine the dependence of specific rock cutting energy (SEc) drilling (SEd) for machines with different operating design characteristics similar breaking mechanics. Laboratory were performed a linear device drill, using measurement system measure electrical power forces force/torque transducers. Field consumption chainsaw machine hydraulic rotary drill under real working conditions in dimension stone quarries. The analysis measured results confirmed strong that devices can be used simulate actual process. In addition, are applicable exploration exploitation phase order assess reduce by optimizing parameters chain cutter and/or drill.
