Underground RC Drilling

Underground Reverse Circulation (RC) Drilling Equipment

As Australia’s market leader in manufacturing premium quality reverse circulation (RC) drill rods and drilling consumables, we’re working closely with companies utilising RC drilling at underground mine operations.

Quickly growing in popularity, underground RC 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

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 6 Benefits of Underground RC Drilling

  • Faster than diamond drilling
  • Cheaper than diamond drilling
  • Larger sample volume
  • Less downstream core processing
  • Increase sample density

Testimonial

“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.”
