Underground Reverse Circulation (RC) Drilling Equipment
RC drilling for underground mining operations is quickly growing in popularity due to it being faster and cheaper than diamond drilling.
Underground RC Drilling
As Australia’s market leader in manufacturing premium quality reverse circulation (RC) drill rods and drilling consumables, we’re working closely with underground RC drillers and their clients to ensure smooth continuity at their mining operations.
Quickly growing in popularity, underground RC drilling provides a route to increasing sampling density and volume, resulting in a much faster and cheaper alternative to diamond drilling.
Harlsan can provide a suite of tough underground RC drilling supplies and consumables specifically designed for underground mining to keep you drilling for longer.
The Benefits of Utilising Underground RC Drilling
THE HARLSAN QUALITY ADVANTAGE
Traditionally, with diamond drilling, sample volumes are not large enough to provide a reliable grade estimate of the area surrounding the drill hole. If your underground operation permits it, RC drilling offers a number of significant benefits over diamond drilling:
The 5 Benefits of Underground RC Drilling
- Faster than diamond drilling
- Cheaper than diamond drilling
- Larger sample volume
- Less downstream core processing
- Increase sample density

“Reverse circulation drilling has proved to be an effective means of providing large representative and high quality samples in open pit gold mines for over three decades. Applying this drilling methodology to underground grade control at Sunrise Dam has demonstrated that it can be as effective as surface RC for defining ore.”

The INLOK Drill Rod Range
QUICKER. SAFER. MORE EFFICIENT.
Any driller who has used a sledgehammer to manually remove a collapsed Inner Tube from an RC drill rod or pipe will know how unsafe it can be. The whole procedure is inefficient and involves injury risk from the associated manual handling.
The Harlsan RC Drilling INLOK™ product range provides a safe and controlled solution to these problems.
