Client: Vale and Carborough Downs Coal Management Pty Ltd
Contract Value: $120M+
Completion: February 2011

Project Overview: NEPEAN Longwall has played a crucial role in managing the longwall installation and ongoing operation of Vale's Carborough Downs underground coal mine with an output capacity of 4.9 million tonnes per annum.

Delivering a NEPEAN Longwall Inbye® longwall system, it a safe and practical longwall installation that has been customised to the needs of the Carborough Downs. A major reason for the success of this installation was that experienced Longwall team identified and remedied system weaknesses during the design and testing phase offsite.

The majority of production shears have been fully automated with LASC enhancement making Carborough Downs a leader in the application of latest automation technology. NEPEAN Longwall re-engineered this technology and branded it as the "Navix System".

Customised inertial navigation technology was incorporated with hardware and software components that were specifically developed for the longwall automation application. Although this longwall automation system has come up trumps in the extensive bench tests, it has yet to be field proven.

The Carborough Downs installation has faced some major challenges, and yet this mine has succeeded to ramp up the longwall operations to forecast production rates compared to some other higher profile new projects that have struggled to meet their production targets.
