Summary:

Illawarra Coal's assets are located in the southern portion of the Sydney Basin within the Southern Coalfield.

The full sequence of Triassic to Permian sedimentary units are present within the Illawarra Coal's areas, including the Permian Shoalhaven Group, Illawarra Coal Measures and the overlying Triassic Narrabeen Group and Hawkesbury Sandstone.

Bulli Coal is the uppermost coal unit in the Illawarra Coal Measures. It is extensively worked in the northern portions of the Southern Coalfield. The Bulli Seam is the main economic coal seam for the Bulli Seam Operation - Appin mine and West Cliff Colliery (now Appin North). It averages approximately 2.6 m thick across Appin, gaining a maximum thickness of approximately 4.1 m. The Bulli Seam thins to approximately 1.4 m in the south eastern part of West Cliff (now Appin North) and also south west of Appin. Overall, the coal thickness for the Bulli Seam is generally consistent across Bulli Seam Operation in the mined out areas and planned areas of longwall mining;

The structure over the Illawarra operation area is relatively well defined based on the geological data available. Seam dips over the area are generally low (1° to 3°).

The faults have been identified by 3D seismic, 2D seismic, underground mapping, underground drilling, de-gassing intra-seam holes and, to a lesser extent, interpreted from floor contours generated from drill-hole data. The faults are predominately extension normal faults.

Fifty-one faults have been interpreted at the Bulli Seam Operation area to a level of confidence that allows them to be incorporated in the geological model. The throw on the Appin faults average approximately 20 m, although the maximum throw is 90 m; approximately 13 faults have throws of greater than 5 m. As the average thickness of the Bulli Seam is less than 2.7 m, a throw of more than 2 to 3 m can adversely impact the potential for eventual economic extraction. This was demonstrated at West Cliff (now Appin North) where LW 22 to 24 were constrained due to faulting. The Appin mine plan has been laid out to avoid the significant faulting identified by exploration to date.

The Bulli Seam Operation has igneous dykes varying from near vertical and thin (less than 0.3 m), which are boggy and soft and easy to mine, to more significant dykes of 4 to 5 m in width which are very hard (up to UCS of 270 MPa) and more difficult to mine. Through geological studies and operating experience, the igneous dykes are understood and have been observed to have narrow contact margins. Hard and wide dykes are being intercepted in the current mining area.


Mining Methods

  • Longwall


Summary:

Appin Mine underground longwall mining operations have transitioned wholly to AA7 and AA9 following completion of longwall mining activities at Appin North (West Cliff Area 5) in early 2016. Appin Mine extracts coal from the Bulli Seam within the Southern Coalfield.

Appin Mine underground longwall mining operations are accessed from three surface locations: Appin North, Appin West and Appin East. Longwall 708A progressed approximately 770 m to finish on 20 October 2019. LW708B commenced mining on 24 April 2020 and as at the end of this reporting period, had retreated 1800 m, with an estimated completion in December 2021.

Extraction of Longwall 903 commenced on 1 November 2019 and was completed in April 2021. On 20 May 2021 LW904 commenced and retreated approximately 195 m as of the end of June. LW904 is estimated to be complete in May 2022.

Ore and Product Stockpiles
No coal is stockpiled at Appin West, as ROM coal is transported underground to Appin East or the WCCPP. The Appin West coal storage bins are currently under care and maintenance.

Appin East has a total raw coal stockpiling capacity of up to 50,000 tonnes. The stockpile is recovered with front-end loaders and transferred directly into the coal haulage trucks for transport by road to either the WCCPP or DCPP.

Appin North operates six primary coal stockpiles for both clean coal and raw coal.

Summary:

Mineral processing facilities include the West Cliff Coal Preparation Plant (WCCPP), the CWEA and the Dendrobium Coal Preparation Plant (DCPP) (located at the Port Kembla Steelworks). The majority of ROM coal from Appin Mine is directed to the WCCPP for processing. The Coal Wash Emplacement Area (CWEA) is used to emplace coal wash from the WCCPP and DCPP (if beneficial reuse options are not available). ROM coal is transported to the WCCPP by:
- coal trucks from the Appin East site, along Appin and Wedderburn Roads; and
- bulk coal winder at Appin North, transported underground from AA7 and AA9.

ROM coal from Appin Mine may also be transported to the DCPP via Mt Ousley on an ‘as required’ basis to maintain work continuity and maintain reduced stockpile sizes at the Appin sites. Clean coal from the WCCPP is trucked to BlueScope Steel (Port Kembla Steel Works) coal handling facilities or to the Port Kembla Coal Terminal (PKCT) for distribution.
