- Community input and engagement.
3. Building a national inventory of derelict mines in Australia
Representatives from NSW (Dr David Blackmore, Director Environmental Sustainability, Division of Resources & Energy, NSW Department of Industry), NT (Dr Mike Fawcett, Director Mining Remediation, Mining Remediation Division, Mines Directorate, NT Department of Primary Industry and Resources), Queensland (Oskar Kadletz, Abandoned Mines Coordinator, Queensland Department of Natural Resources and Mines), SA (Antonia Scrase, Principal Officer, Mine Closure, SA Department of State Development), WA (Karen Caple, General Manager Administration and Reform, WA Department of Mines and Petroleum) and Tasmania (TBC) will present on:
- Number of derelict mines, including historical perspectives in each state
- Policies relating to the management of derelict mines and when potential adverse impacts of such sites were first recognised
- Current management strategies
- Government perspectives towards management of derelict mines
- Land-use patterns and stakeholders proximal to derelict mine sites
- Policy and technological gaps
- Standards and regulatory measures
- Policies relating to mine closures and rehabilitation
- Ownership and liability issues.
4. Approaches to managing derelict mines
The session will comprise an overarching approach to managing derelict mines and case studies from across Australia that will focus on:
- Developing an appropriate response to the Australian Derelict Mines problem – Peter Nadebaum, GHD
- SA: The Brukunga mine site and lessons of a long-term remediation strategy – Dr Raul Mollehuara, Project Director & Operations – Brukunga Mine, SA Department of State Development
- NSW: Woodsreef asbestos mine major rehabilitation project – Dr David Blackmore, Director Environmental Sustainability, Division of Resources & Energy, NSW Department of Industry
- Queensland: Mount Morgan mine site: long-term site management – Oskar Kadletz, QLD Department of Natural Resources and Mines
- Tasmania: Savage River magnetite mine Rehabilitation Project – Colleen Cole, Manager, Scientific and Technical Branch, EPA Tasmania
- NT: Redbank copper mine – Mike Fawcett NT Department of Primary Industry and Resources.
5. Understanding community perspectives
This session recognises the concerns and perceptions of Indigenous peoples, farmers and other communities. Presenters will discuss the strategies that mining companies and the Minerals Council of Australia have in place for dealing with derelict mines in a community context.
Topics in this session include:
- Keynote address – Derelict mines: ownership past present and future – Professor Tim Roberts, Director Tom Farrell Institute, University of Newcastle
- A portfolio of rehabilitation and remediation experience in Minerals Australia – Gavin Price / Stephen White, BHP Billiton Minerals Australia
- Managing rehabilitation and closure to avoid derelict mines – Stuart Ritchie, Rio Tinto.
6. Risk-based management of derelict mines
A risk-based approach to managing contaminated or degraded sites is now recognised as the most cost-effective, reliable and sustainable strategy. Following a keynote address emphasising the critical elements of this approach, the session will focus on case studies of the successful risk-based management of several abandoned mines.
Topics in this session include:
- Risk and reputation management matters associated with the risk communication management of derelict mines – Barbara Campany, GHD
- Inert atmosphere installations – a new approach to controlling AMD discharges from underground mines – Jeff Taylor, Earth Systems
- Application of a risk-based approach to sites in NSW – Dane Lamb, University of Newcastle.
