Byrnecut Australia - Wira Haulage Shaft

pitt&sherry supported Byrnecut throughout the delivery of the Wira Haulage Shaft at Prominent Hill, a 1,300 m deep, 7.5 m diameter production shaft designed to increase mine production capacity. Building on the early geotechnical framework developed for the project, our team provided integrated geotechnical, civil, structural, mechanical and electrical engineering services from construction planning through to shaft completion. 

Our geotechnical involvement included temporary ground support design, raisebore stability assessments, fibrecrete QA/QC, instrumentation monitoring and continuous 24-hour geotechnical coverage throughout shaft sinking. Working closely with Byrnecut, we helped implement an innovative near-boltless fibrecrete support system supported by real-time ground assessment and LiDAR-based mapping technologies, improving both safety and construction efficiency

In parallel, pitt&sherry provided construction-phase engineering support including permanent liner design, proof engineering for sinking stages and lifting systems, topside structural engineering, mechanical and electrical engineering services, temporary works verification, design coordination and technical support aligned with shaft sinking operations. Our team worked collaboratively with Byrnecut to manage design interfaces, respond to changing ground conditions and support safe, efficient construction through to completion and commissioning.
