Business Summary
Mine subsidence is the movement of the ground following the extraction of coal. After coal is extracted beneath the surface, the land above can sink. There are many contributing factors to mine subsidence. Subsidence can cause damage to buildings and other structures. Subsidence impacts to buildings and other structures vary depending on the depth o Subsidence impacts to buildings and other structures vary depending on the depth of the mining, the geology of the land, and how the coal was extracted. Subsidence caused by old inactive mines is generally localised and only affects a small area. Sometimes, collapses in the old mine workings result in a hole in the ground surface known as a 'subsidence hole'. Most active underground coal mines that operate throughout New South Wales today use longwall mining methods. Subsidence from longwall mining generally occurs over a large area, within a short time after the coal is extracted. This means there are minimal long term subsidence risks.
About Us

Subsidence Advisory NSW is an agency of the NSW Department of Customer Service and operates under the Coal Mine Subsidence Compensation Act 2017.

Changes to the mine subsidence system in NSW took effect from 1 January 2018 following a review of the former Mine Subsidence Compensation Act 1961. The changes make the mine subsidence compensation processes easier for property owners and provide a more equitable model for mining operators.
