pressure on drilling due to increased iron ore production Description

  • What is RC Drilling? | Harlsan Industries, Australia

    10/28/2019· Western Australians are proud to claim RC drilling as our invention, and it's said to have originated in Kalgoorlie in the mid-20th Century when traditional open-hole drilling was proving difficult in soft iron ore and mineral sands. As time moved on, so did technology, and 1972 saw the first specific RC drill pipes developed.
