Welcome to United Collieries
United Collieries Pty. Limited (United) was formed in 1980 and operates an underground coal mine approximately 16 kilometres west of Singleton in the Upper Hunter Valley of New South Wales. As of December 1999 United’s ownership comprises 95% Xstrata Coal Pty. Ltd. and 5% Construction, Forestry, Mining and Energy Union (CFMEU).
In June 2009, Xstrata Coal announced that due to an assessment of geotechnical constraints, plans to mine Longwall Panel 11 were to be abandoned, and hence United would cease production following the completion of Longwall Panel 10.
In March 2010, once the extraction of equipment from the underground was complete and the necessary sections of the underground sealed, United Collieries entered into a period of Suspension of Operations.
