The Hunter's coal industry has been dealt a blow with Centenninal Coal shutting down it's Wyee and Lithgow mines.
As a result, 40 workers from both locations will be made redundant, with the rest of the workforce being redeployed.
Centenninal Coal points to falling coal prices and rising production costs as being to blame for the decision.
Meanwhile, Port Waratah Coal Services has announced the proposed plans for the controversial T4 coal loader at Kooragang are being significantly downsized.
While the original plan was for the facility to process 70 million tonnes of coal a year, this has been reduced to only 25 million tonnes.
The company is still confident that the terminal will be built.
