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.
