In a presentation by its senior executives, BHP coal president Dean Dalla Valle said the company would continue with existing committed expansions while squeezing out as much productivity from existing assets as possible.
"Our operational focus is to maximise utilisation of installed capacity," he said.
"A substantial increase in metallurgical coal volumes will underpin lower unit costs.
"We will continue to optimise our energy coal production mix with a focus on high margin export volumes."
The company will seek to recover latent capacity, complete projects in execution and debottleneck installed capacity.
BHP's Queensland coal division is producing at 100% of supply chain capacity and by financial year 2015 capacity will be more than 40% higher than FY2012 production.
"Capital expenditure will peak in FY13," coal finance vice president Gideon Oberholzer said.
"No new major projects are being considered.
"Our capital expenditure profile will trend towards the rate required to sustain our operations in the medium to long term.
"We are 'long' resource and have sustainably reduced exploration expenditure."
Oberholzer said strong progress has already been achieved.
"We have successfully renegotiated terms with some contractors while other contracts have been terminated," he said.
"We have optimised the use of hire equipment and rationalised the mining fleet.
"We have renegotiated terms with suppliers of bulk consumables, spares and maintenance services. We have delivered significant savings and will continue to pull the productivity lever hard."
Coal project development vice president Phil Hynes said Daunia and Broadmeadow projects in Queensland were successfully delivered.
The Broadmeadow project extends mine life and increases capacity by 400,000 tonnes per annum, with first production achieved in March 2013, ahead of schedule.
It is forecast to ramp up to nameplate capacity by the fourth quarter of calendar year 2013 and has longwall top coal caving which provides upside potential.
Daunia is a 4.5 million tonne per annum greenfield mine development with first production achieved in March 2013, ahead of schedule and under budget.
It is forecast to ramp-up to nameplate capacity by Q4 CY2013.
Hynes said BHP Billiton's Illawarra Coal Appin area 9 project in New South Wales was progressing to plan with a budget of $US845 million.
The project is 40% complete with initial production expected in CY2016. Appin area 9 will have production capacity of 3.5Mtpa.
Two longwall domains will largely use existing infrastructure, personnel and longwall equipment.
