A bid to extend mining operations on the Blagdon Estate has been approved.
Banks Mining will extract an additional 290,000 tonnes of coal from its Shotton surface mine by working a new area on the western side of the site.
The newly named Shotton Triangle will be mined at the same time as existing operations over two years so the whole site is still set to be restored by October 2019.
The extension will help to sustain about 150 jobs.
Planning permission for the work has been granted by Northumberland County Council, which approved a separate application this summer for mining at Shotton South West elsewhere on the site.
Banks’ Environment and Community Director Mark Dowdall said: “The Shotton surface mine operates in a safe, responsible and efficient way, and enables us to make significant long-term contributions to both the local and regional economies.”
