Investigation on the Effect of Drilling Speed and Pressure Force on Energy Consumption

With increasing industrialization and the development of mining, drilling work has increased in recent years in the world. In mining, holes are drilled in rock for many purposes. Many factors influence the performance of the machines during drilling of the rocks with different equipment. Researchers continue to work on changeable parameters, including these factors, for a more efficient drilling operation. In drillability analysis, drilling speed is an important indicator. It is desirable that the drilling speed is generally high so that efficient drilling can be achieved in the rock material. But the procedures applied to increase the drilling speed cause the exhausted energy to increase. For this reason, it is very important for the mining projects that the energy consumption can be predicted beforehand in the drilling process. In this study, drilling experiments were carried out in seven different rock units at 11 different pressing forces and at four different rotational speeds. The change in power consumption obtained from drilling experiments was investigated. In addition, some equations have been developed by evaluating the relationship between drilling speed and energy consumptio
