Mine Rehabilitation Process
 
Alcoa Anglesea takes pride in the rehabilitation work we undertake following our mining operations. Through continuous improvement in our rehabilitation techniques, we have achieved significant species return and richness rates in our rehabilitation areas. We commit ourselves to further improve on these good results and the way we document and plan our rehabilitation work.
 
The open cut brown coal mine at Alcoa Anglesea has been carrying out progressive mine rehabilitation since the 1970s.
 
Alcoa Anglesea aims to minimise the environmental effects of its brown coal mining and leave a positive legacy in the local area from its operations.
 
Mine rehabilitation is an ongoing process, where the mined out areas are back-filled using large excavators and dump trucks. The overburden that is removed from the top of the coal reserves is used to back-fill the hole created by mining.
 
Once the return of the overburden is completed: a minimum of one metre of clay/gravel that is found naturally below the topsoil and subsoil is replaced; the subsoil and topsoil is then replaced in the same order it was removed; the landscape is ripped on contour with a large tractor to prevent water run-off and erosion; and carefully preserved mulch that is gathered in the land clearing process is laid down and allowed to regenerate naturally. We then survey our mine rehabilitation areas annually to monitor how they are progressing and determine whether any hand planting is required.
 
This process results in the restoration of a self-sustaining eco-system.
