Centennial Coal is set to restructure its underground Myuna Colliery at Wangi Wangi in New South Wales, Australia.
The company's latest decision comes in response to the challenging geological conditions faced by the mine, coupled with the ongoing economic downturn in the mining sector, and will result in the loss of up to 30 jobs.
According to the company, Myuna has been extracting coal from three different seams under Lake Macquarie for nearly 40 years.
The restructuring will result in the transfer of 21 employees from the mine, which currently employs 255 people.
The company has already transferred 11 of the employees and the remaining ten employees will be shifted in the next week from Myuna to Centennial's Mandalong Mine at Morisset.
Myuna Colliery is linked through a overland coal conveyor to its customer Eraring Power Station.
In 2010, Myuna submitted project approval under Part 3A of the Environmental Planning and Assessment Act to go ahead with mining in areas outside the existing development consent mining area, as well as within existing mining leases.
The mine received approval for the continuation of mining until 31 December 2032 in January 2012.
