Ravensworth Underground Mine (RUM) is in the Hunter Valley coalfields of NSW, about 25km northwest of Singleton. RUM has been managed by Xstrata Coal NSW since February 2008 and is a joint venture operation between Resource Pacific (owned by Xstrata Coal and Marubeni) and Korean steel manufacturer Posco.
The Ravensworth coal handling preparation plant and the Ravensworth coal terminal operate at the RUM site, and are utilised by RUM for coal preparation and loading purposes.
RUM was developed for longwall extraction, to extract a large semi soft coking coal reserve. The mine operates 24 hours a day, 5 days a week, producing a semi-soft coking coal that can be blended with hard coking coal and used in steel production or for power generation.
