Case Studies

Mining: Lonmin Rowland Shaft

The Challenge

Completion of 4.5m diameter x 985m length at 90º shaft with ground hardness between 200 MPa and 250 MPa. There were a slight deviation of 350mm

Our Solution

Master Drilling addressed the following project challenges:

  • Work had to continue amid a six-month mine strike
  • Lading had to take place via the funky slide method – this is where rocks are loaded with a winch onto a belt and then carried over into a hopper in order to be transported out of the mine

The Result

  • The project was completed on budget, within stipulated time frames
  • 100% safety record achieved
  • Three local community members formed part of its drilling crew
