Find out how the landscape is repaired after open cut mining.
This is a PowerPoint presentation showing rehabilitation work
carried out at the Ensham open cut coal mine in Central
Queensland. The slides are predominantly pictorial and
illustrate the processes of planning, removal and stockpiling
of overburden, mining, surface reshaping, return of topsoil,
planting and monitoring.
Part 1 – This PowerPoint introduces the Ensham open-cut coal
mine located in near Emerald in central Queensland. The
process of ‘progressive rehabilitation’ is explained using
diagrams. Maps of the rehabilitation plan, ecosystems and
vegetation are also included.
Part 2 – This PowerPoint explains the processes involved in
spoil pile construction and rehabilitation.
Part 3 – This PowerPoint explains the method of topsoil
collection and its use in spoil pile rehabilitation.
Part 4 – This PowerPoint explains the sequential processes
involved in revegetation from species selection to use of
fertiliser and mulch in the rehabilitation process.
Part 5 – This PowerPoint examines the planting of trees as
part of the rehabilitation process, introduces an
environmental engineer and provides an insight into the costs
around rehabilitation.
