Hydro Power Drilling

Energy Efficient Drilling (Hand held)

Water operated hand held rock drilling is an efficient and effective way of mining compared to air, electric or oil hydraulic powered equivalent machinery in terms of ton of water / ton of rock and kWh/m drilled.

Rock drills are either used with its own pump set (AquaPack) which is in close proximity to where the drilling is taking place (typically within 20 m) or powered by a remote located pump set (centralized pumping station) which typically feeds 10 rock drills off 1 power pack.

In both cases, water is recirculated i.e. closed loop system other than the flushing water which is approximately 20% of the water used of powering the rock drill. This is done by using our latest technology in PLCs/variable speed drives/mechanical unloading systems/permanent magnet motors or a combination of some or all of the above.
The HPE rock drill returns water back to the pump at max 20 bar, thereby allowing water to be “pushed” back into the pump suction line.
