Peabody Energy is looking to extend the life of its North Wambo underground coal mine by six months with the development of an additional longwall.
The coal miner has lodged an application with the Department of Planning asking for permission to build the longwall by 2015.
Peabody said the extension will allow it to recover an additional 1.9 million tonnes of coal and will result in marginal increases of total rejects from the mine’s CHPP.
It said the longwall should be able to be developed using existing environmental management and monitoring measures.
Public exhibition of the proposal ends on the 17th of October.
