Deposit Type

  • Sedimentary


Summary:

The resource coal targeted for extraction at Ravensworth Operations includes seams of the Foybrook and Burnamwood Formations, which form part of the Wittingham Coal Measures. The coal seams targeted extend from the shallow Broonie Seams, through the Bayswater, Lemington, Pikes Gully, Arties, Liddell and Barrett Seams, to the Hebden Seam. The strata dips gently (<5 degrees) to the south-east within the mine towards the Bayswater Syncline and flattens to the south-west around the Ravensworth North monocline. A thin igneous dyke runs through the pit area on a north-easterly orientation and intersects a small volcanic plug in the north of the pit area. This volcanic breccia has been well defined by drilling.

Spoil material is regularly tested to determine the quality of material for rehabilitation. Recent soil testing on spoil material from Ravensworth indicates the following:
- Spoil material tested was alkaline, highly saline and strongly sodic;
- The effective cation exchange capacity (eCEC) is moderate, indicating good nutrient retention and holding capacity;
- Certain soils are dispersible due to their sodicity and magnicity and should be managed accordingly;
- Phosphorus levels are suited to P sensitive plantings, including Australian natives; and
- Where required, Gypsum will be applied to assist in balancing the cations and preventing dispersion.


Mining Methods

  • Truck & Shovel / Loader


Summary:

During the reporting period, mining and coal preparation occurred at the Complex at Ravensworth North and RCHPP. RUM has remained in care and maintenance from October 2014.

No mining was undertaken at Narama, Narama West pit and RUM during the 2021.

Mining during the MOP period is planned to continue in the currently operating Ravensworth North mining areas. Operations at Ravensworth North are scheduled to continue throughout the MOP period and beyond until 2034.

Ravensworth North is a multi-seam open cut mining operation located immediately west of Bayswater Creek. The mining area is progressing southwards into the former Ravensworth West Open Cut mine. The completed mining in the northern extent of this mining area is adjacent to the former Cumnock underground mine workings.

Ravensworth North is the active mine for Ravensworth Open Cut (ROC).

Mining is currently undertaken using truck and shovel methods, although Ravensworth Operations Pty Limited (ROPL) has approval to operate a dragline, if required.

Mining Process
Areas planned for mining are surveyed and suitable topsoil is stripped and made available for rehabilitation purposes.

Overburden to the first seam and subsequently each section of inter-burden between the coal seams is drilled and blasted or ripped by bulldozer. It is then loaded by shovel, excavator or loader into trucks which haul the material to emplacement areas at design ........
