Together we deliver


Monadelphous has a strong reputation for the safe and reliable delivery of engineering construction, maintenance, and electrical and instrumentation services to the coal industry.

We provide comprehensive structural, mechanical and electrical, specialist dragline and shovel shutdown, maintenance and erection services.

Monadelphous entered the coal market with two projects in New South Wales (NSW) in 1991 for the supply, manufacture and installation of coal bins and associated mechanical works. Our first coal maintenance contract was in 2000 with the purchase of our Muswellbrook operation in NSW.

Following this work, Monadelphous was awarded projects at coal mines and terminals in Queensland and NSW.

In July 2004, Monadelphous secured milestone work at the Rolleston Coal project in Queensland. The project included construction of a purpose-designed and built stacker, which provided a competitive advantage over imported equipment. This won multiple awards including an Award for Excellence from the Association for Consulting Engineers Australia.

Monadelphous secured its first dragline shutdown, in Queensland, with BHP Billiton Mitsubishi Alliance at its Blackwater mine in 2009. This led to further work and a preferred-supplier standing with many of the large coal mine operators.
