The Hole Truth: The mess coal companies plan to leave in NSW
by Adam Walters, Energy & Resource Insights, June 2016.
Booming demand for coal exports in recent decades has seen the proliferation of huge open cut coal mines across NSW. In Australia, when these mines cease production their owners are not required to fill in the pit that remains. These “final voids” may be hundreds of metres deep and kilometres in length and their impact and scale is poorly understood. This report identifies the probable scale of currently approved final voids in NSW, particularly the Upper Hunter – and the gaps in scientific knowledge, often related to a lack of detailed studies for each final void as well as the lack of regional studies which integrate all current and former mines.
