Adani's proposed Carmichael mega-mine in central Queensland will have a disturbance footprint of 28,000 hectares, which is an area greater in size than North Stradbroke Island.
If it proceeds this mine will permanently alter the landscape, leaving behind extensive waste dumps that are at risk of failing in the long term, alongside final voids that are predicted to drain adjoining groundwater permanently.
The Adani mine is the just one of the nine proposed new 'mega' coal mines in the Galilee Basin, the last remaining major coal province yet to be developed in Queensland.
The proposed Galilee mines will comprise over 34 open cut pits and 11 underground mines along a 270 kilometre north-south strike, to produce over 300 million tonnes of coal per annum.

Our 2014 report, Railroaded, looks at the consequences of carving up food lands for coal transport in Central Queensland.
The Bowen Basin, also in Central Queensland, contains the largest coal reserves in Australia. These reserves have been mined extensively over decades at a significant cost to the natural environment, farmland and water resources.
The long term legacy from coal mining in Central Qld will be a string of un-rehabilitated final voids- large holes in the ground left over after an open cut mine that are often filled with toxic water. Read more about Lock the Gate's mining rehabilitation campaign here.
More on the Adani mine...
The Carmichael coal mine Supplementary EIS estimates groundwater take of 26ML/day in year 2029, which equates to UP TO 9.5GL/year.
The current groundwater licence for the mine is inadequate because:
- It does not contain a limit on the volume of groundwater that can be extracted - ie it is unlimited.
- It extends until 2077 and does not include any independent review process at any stage, and does not stipulate a mechanism to stop the mine if the impacts are found to be too severe.

Mining legacy & rehabilitation costs of Adani mine:
Adani predicts that there will be a loss of landscape functionality and land use utility across all land classes after mining.
At least 88km of watercourses will be diverted for the mine and there will be no attempt made to restore them after the project ends.
Analysis by Lock the Gate Alliance estimates that it would cost at least $1.5 billion to rehabilitate the Adani Carmichael coal mine in Central Queensland. Download the 2017 report here.
An earlier report shows that the proposed rehabilitation of the Adani Carmichael coal mine will fail even mining industry standards. The mine will leave 3,346 hectares (an area almost 30 times the size of the Brisbane CBD) as final voids - holes that will never be filled and will remain un-rehabilitated.
