Mine Subsidence: Legal and
Technical Considerations
Navigating Mine Subsidence Risks in Sydney
Sydney’s history of coal mining has left pockets of unstable land, where subsurface voids can collapse, causing sudden subsidence. Under the Mine Subsidence Compensation Act 1961 (NSW), property owners may claim compensation for damage, but proving causation requires rigorous geotechnical analysis.
Key Challenges
We bring in-depth knowledge and hands-on experience to support complex geotechnical and construction-related matters.
-
Risk Assessment
Mapping historical mine workings using NSW Department of Planning data to evaluate subsidence potential.
-
Damage Mitigation
Designing remedial solutions (e.g., grouting) to stabilise affected sites.
-
Compensation Claims
Differentiating mine-related subsidence from other causes (e.g., soil shrinkage) to validate claims.
Case Study
In Wollongong, our team linked structural cracks to a longwall coal mine, securing a substantial compensation payout. We combined geotechnical investigations with archival research to demonstrate liability.
Legal Compliance
Developers in mine-prone areas must submit subsidence mitigation plans to local councils. Our firm ensures compliance with AS 2870 and NSW Planning Guidelines, reducing legal exposure.
