CPC Engineering (CPC) was engaged by AngloGold Ashanti to design and deliver the emergency egress ladder and rising mains at the new underground Boston Shaker mine which is being developed within the Tropicana gold mine in Western Australia.

With the project ready for rollout, COVID-19 restrictions were implemented resulting in a number of projects across the country being put on hold. CPC’s fast response allowed the rearrangement of schedules and onsite accommodation to ensure project delivery as promised.

“CPC prides itself on its close and lasting relationships with its clients, together with its culture of ‘Safer by Choice’”, said Glen Weir, CEO, CPC. “This could not be better demonstrated than with the successful delivery of this project, as the COVID-19 pandemic gripped Australia.”

In a matter of just 4 weeks, the CPC team established themselves onsite, completed the installation and pressure tests to deliver the completed project.

“We were able to achieve this by working closely with the client,” said Project Manager, Brett Mais. “Together we were able to find a way to minimise disruption as the COVID-19 restrictions were applied, while also ensuring that the health of our team and the community wasn’t at risk.”

The 250m depth from the surface provided no constraint to the CPC team in delivering the emergency egress ladder and rising mains of the same length.

Meticulous design and engineering were key to the successful delivery of the innovative solution which integrated dewatering, potable and service/fire water, and compressed air pipes into the structure.  This ensured space was maximised while providing a safe exit from the underground mine in an emergency.

A trial assembly prior to installation was completed to confirm that all 20 identical modules fitted perfectly, supporting a seamless installation.
