Main Content

Myuna is an underground coal mine located in Wangi Wangi, Lake Macquarie in the Newcastle Coalfields approximately 25 kilometres south-west of Newcastle.

In 2010 Myuna submitted a Project Approval under Part 3A of the Environmental Planning and Assessment Act to continue mining in areas outside the existing Development Consent Mining Area and within the existing mining leases. In January 2012, Myuna received Project Approval for the continuation of mining until 31 December 2032.

This approval extends mining and coal handling at Myuna within the lease area and proposes to:

  • mine using bord and pillar mining methods in the Wallarah, Great Northern, and Fassifern seams in CCL762 and ML1370, for a further 21 years;
  • produce, handle and distribute to Eraring Power Station, up to 2 million tonnes per annum (Mtpa) using existing infrastructure;
  • continue the use of ancillary infrastructure and service for a further 21 years;
  • upgrade the water management system; and
  • rehabilitate the surface facilities within 5 years of completion of mining.

Myuna had an excellent year in 2011 achieving new production records. Myuna places a large amount of emphasis on safety and environmental improvements. At the 2011 Centennial Coal Health Safety Environment and Community Innovation Conference Myuna was awarded both the Judges and Peoples First Place Award.

The mine prides itself in maintaining strong partnerships with local community groups in Wangi Wangi. An example of our ongoing sponsorships include:

  • Wangi Lions Club and the Dobell Arts and Craft Festival
  • Wangi RSL Amateur Sailing Club and the Australia Day Regatta
  • Sponsorship of the Wangi Arcadia Netball Club
  • Sponsorship of the Wangi Lions Club Beautifying Wangi Project
  • Toronto Learning Community Band through the Arcadia Vale School
  • Rathmines Scouts

Mining Operations Plan / Rehabilitation Management Plan

Mining operations in NSW are required, as a condition of an authorisation issued under the Mining Act, to conduct mining operations in accordance with a Mining Operations Plan (MOP) that has been approved by NSW Trade and Investment - Division of Resources and Energy.
The MOP describes the manner in which mining, processing, rehabilitation and reporting are to be undertaken with reference to Management Plans and Procedures. The MOP also establishes relationships to other approval and reporting requirements consistent with development consent, leases and licences.

Pollution Incident Response Management Plan

The Pollution Incident Response Management Plan has been developed to satisfy the requirements of the Protection of the Environment Legislation Amendment Act 2011 (POELA Act) which requires the preparation, implementation and publication of a Pollution Incident Response Management Plan.
The objectives of these plans are to provide guidelines and procedures for the effective control and reporting of pollution incidents to all relevant stakeholders.
Whilst personal contact details for the following document are available in the controlled on-site Pollution Incident Response Management Plan, they do not appear in this public document under provision of the Privacy and Personal Information Protection Act 1998.

Subsidence Management

Subsidence Management Plans (SMPs) are prepared by mining lease holders to consider the potential impacts of underground mining and identify measures to manage such impacts. SMPs may contain requirements for the avoidance of damage to particularly significant features, the mitigation of damage, or rehabilitation of subsidence related impacts.
