Deposit Type

  • Sedimentary


Summary:

Geologically the Mandalong Area is located in the south-west of the Newcastle Coalfield, a geological subdivision of the north-eastern Sydney Basin. The coal deposits of this area are contained within sedimentary rocks of the Late Permian Age Newcastle Coal Measures, which are characterised by complex patterns of splitting and coalescence of the various coal seams.

The significant coal seams within the Area are the Wallarah, West Wallarah, Great Northern and Fassifern Seams. The term “West Wallarah Coal Seam” was introduced by Centennial Mandalong and has been used at Mandalong Mine to define the coal seam formed by the westerly convergence of the Wallarah and Great Northern Seams.

Other significant units, which lie within the stratigraphic section, are the Awaba Tuff Formation, which lies between the West Wallarah and Fassifern Seams, and the Munmorah Conglomerate, which sits within the Triassic Age Narrabeen Group sediments between 80 m to 110 m above the West Wallarah Seam and Wallarah-Great Northern Seams. This conglomerate beam has a significant impact on the subsidence profile for the Mandalong Mine due to its spanning potential.


Mining Methods

  • Longwall
  • Continuous
  • Bord-and-pillar


Summary:

Mandalong Mine is a modern underground longwall operation located on the western side of Lake Macquarie near Morisset and west of the M1 Motorway. The Mine is situated approximately 130 km north of Sydney and 50 km from the Port of Newcastle, supplying up to 6.5 million tonnes of coal to the domestic power and export markets.

Mandalong Mine comprises the underground workings and surface infrastructure of:
• The Mandalong Mine underground workings including longwall panels, development units and surface infrastructure located near Morisset;
• The Cooranbong Entry Site, consisting of the Cooranbong Colliery underground workings and surface infrastructure located near Dora Creek;
• The Mandalong South Surface Site located off Mandalong Road; and
• The Delta Entry Site, which encompasses an entry and coal delivery system, located near Wyee at the Vales Point Rail Unloader Facility.

Centennial Mandalong has approval to use longwall mining and bord-and-pillar mining methods to extract up to 6.5 Mtpa of ROM coal from the West Wallarah and Wallarah-Great Northern Seams.

The proposed mine plan within the Southern Extension Area encompasses a total of 40 longwall panels ranging in length between approximately 1,000 and 3,500 metres, depending on seam conditions and site constraints, and ranging in width between 160 and 200 metres.
