Summary:
Underground mining operations are approved at a maximum extraction rate of 4.5 million tonnes per annum (Mtpa) of run-of-mine (ROM) coal until 31 December 2035 under PA 08_0101. This approval allows longwall mining of the Hebden, Barrett and Middle Liddell seams to produce high quality, semi-hard coking coal for export.
Integra Underground was placed under care and maintenance in May 2014, during this time environmental management of the site was maintained under a Care and Maintenance Environmental Management System. Operations recommenced in 2017, with development resuming in February 2017 and longwall extraction resuming in May 2017. The reporting period (2018) is therefore the first full year of mining operations since being placed under care and maintenance.
Integra Underground completed secondary extraction of Longwall 13 in July 2018 and commenced secondary extraction of Longwall 14 in early September 2018. Development of first workings for Longwalls 15 and 16 continued in 2018, with secondary extraction of Longwall 15 due to commence in late July 2019.
