Rocky’s Reward is an open pit nickel mine within Nickel
West’s Leinster mine complex, located 400km north of
Kalgoorlie.

Details

Ausdrill engaged Fortec to install drape mesh to the north wall of the pit. The remediation concept selected consisted of a high tensile drape system which would allow the rocks to fall, but in a controlled manner, guiding them to the toe of the slope to minimise bounce height and potential kinetic energy.

This allowed the design boulder to be controlled during a potential rockfall between the mesh drape and the rock face, without compromising the system with the loads transferred
through the mesh and into the top anchors and cables.

The scope included installation of:

  • Drapery mesh covering an area of 60m long in pit strike direction and 70m to 90m high following slope profile.
  • 21 anchor points, drilled and grouted.
  • Installation of 8mm cable.
  • Scaling of rock face by rope access technicians for lapping and clipping joints.

Highlights

  • All works were self-performed by Fortec.
  • The project was completed on time and to clients satisfaction.

Capabilities

  • Slope Stabilisation
