In 2013, the Millennium mine achieved record clean coal production and sales of 3.4 million tonnes, had a total cost reduction of 20 per cent and reached over one million man hours without a lost time injury.
The mine achieved these milestones all whilst transitioning from a contractor-run mine to an owner-operator model.
Peabody attributes its success to improvements in mine planning, mining method, pit setup, organisational culture and fleet configuration which included the introduction of an electric shovel which had not been used at the site before.
Millennium has used an innovative approach to extracting its resource by using multiple mining methods across the mine based on the geology, pit conditions, and cost effectiveness.
A combination of strip mining, terrace mining, and dozer push is utilised at the site.
An electric rope shovel was also introduced which has been set up to maximise overburden and increase overall productivity.
The mine also created a streamlined production model where better planning of dumping and efficient sequencing of mining blocks has encouraged high fleet productivity.
Additionally, the redesign of haul roads and introduction of real-time equipment health monitoring has improved the availability and reliability of equipment fleet.
It has also increased the feed to the coal washing plant through short interval controls and operational focus which greatly contributed to the record of the amount of clean coal production in 2013.
Peabody said the culture of the mine has been critical to its success and is demonstrated through the mine's focus on a positive attitude and behaviour towards safe production, operational efficiency, value stream-based decisions, personal accountability, and performance-based recognition.
Millennium mine is located in Queensland's Bowen Basin and produces coking and PCI coal for export to Japan, Korea, China and India.
With Millennium located adjacent to BHP Mitsui Coal's Poitrel project, the two companies have agreed to share infrastructure through the Red Mountain joint venture.
Operations at Millennium began in 2006, and the mine employs 475 people.
