​Welcome to United Collieries

United Collieries Pty. Limited (United) was formed in 1980 and operated as an underground coal mine approximately 16 kilometres west of Singleton in the Upper Hunter Valley of New South Wales. United's ownership comprises 95% Glencore Coal Pty. Ltd. and 5% Construction, Forestry, Mining and Energy Union (CFMEU). In June 2009,United 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.

In November 2014, Glencore and Peabody agreed to form a 50:50 Joint Venture to develop an opencut coal mine Project that will combine the existing open cut operations at Wambo Coal with a new opencut at United Collieries. It is proposed that Glencore will manage the combined opencut mining operations utilising Wambo Mine's existing infrastructure. Peabody will continue to operate the Wambo Underground, the Coal Handling and Preparation Plant (CHPP) and rail facilities.

The United Wambo Open Cut Coal Mine Project - SSD 7142 (the Project) Preliminary Environmental Assessment (PEA) was submitted to the Department of Planning and Environment (DPE) on 30 June 2015. The United Wambo Open Cut Coal Mine Project Development Application and Environmental Impact Statement (EIS) was lodged with the DPE on 11 August 2016, the EIS for the Project was placed on public exhibition from 11 August 2016 to 22 September 2016. During the public exhibition period 103 submissions were made on the Project, including 78 from the community.

On 12 November 2018, the then DPE presented their Final Assessment Report to the Independent Planning Commission (IPC) and considered that the Project and associated modifications to Wambo consents were approvable subject to conditions.

On 29 August 2019 the NSW Independent Planning Commission (IPC) approved with conditions the United Wambo Open Cut Coal Mine Project.
