The mine is capable to operate for around 60 years and has potential for further expansion. It will initially produce up to 5.5 million tons of metallurgical coal a year.
BHP Billiton coal president Dean Dalla Valle said: "The operation will produce metallurgical coal for the steel industry and has been constructed with the latest technology to be one of the most productive, sustainable and highly performing metallurgical coal mines in the world.
"Energy efficiency is a key focus for the mine and was built into its design and management system.
This includes the use of highly efficient equipment and the optimisation of truck, shovel and dragline movements.
"This improves the efficiency of our energy use and helps minimise our greenhouse gas emissions."
Mitsubishi plans to expand equity production to improve supply of metallurgical coal and cater to global demand, including Japan.
The project has supported the region with 500 new jobs.
