Grosvenor TBM – Delivery Support

In July 2012 construction started on the $1.7B Grosvenor project, a five million tonne per annum underground longwall mine near Moranbah in Central Queensland. With a projected mine life of over 25 years, Grosvenor will be a world class operation.

In a first for the Australian mining industry Anglo American utilised a tunnel boring machine (TBM) for drift excavation operated by mining contractor, Redpath Mining. High gas content in the geology, and stringent coal mining legislation presented a unique challenge that required innovative and unique TBM methods to achieve project success.

Bamser Involvement In The Project

Bamser were engaged by Redpath Mining to provide an experienced tunnel engineer to assist with the detailed planning of the “roll-out & recovery” phase for the 8m Robbins TBM following completion of the first drift. This scope was expanded, and Bamser were retained to assist Redpath with day to day management of TBM operations and advise on technical improvements to the TBM for increased safety and efficiency in the second drift. Support was provided in;

• Detailed planning & Methods preparation,
• TBM modification recommendations including cost-benefit analysis & design coordination,
• General tunnel engineering duties,
• Procurement recommendations ,
• Subcontractor management,
• Project Scheduling.
