Summary:

Surface soils in the Wangi area and proximate to the surface facilities are classified as part of the Awaba erosional landscape on the Lake Macquarie to Gosford. The Awaba soil landscape is associated with the Munmorah Conglomerate Formation of the Narrabeen Group, and the Newcastle Coal Measures. The topography of this landscape typically comprises low hills with short side slopes and numerous closely spaced drainage lines. Rock outcrops are usually absent and lenses of mudstone and tuff may occur. This soil landscape generally has a high erosion hazard.

Myuna Colliery has extensive workings in the Wallarah, Great Northern and Fassifern seams and has been extracting coal for over 30 years. The area covered by the Colliery is located in the centre of the Newcastle coalfield, a geological sub-division of the North Eastern Sydney basin. The coal deposits of this area are contained within sedimentary rocks of the late Permian age Newcastle Measures. The coal seams typically extend deeper to the south, therefore a higher depth of cover is observed.

Mining activities are concentrated in the Great Northern and Fassifern seams, but could include workings in the Wallarah seam.
