Abstract:Several hydraulic circuits designed for underground and surface hydraulic drill rig have been analysed aimed at saving drilling energy, namely, drilling with maximum power efficiency and minimum"design pressure loss". The results are useful for guiding the design of hydraulic drill rig.
Key words: hydraulic drill rig hydraulic power source disposition energy consumption
