Ravensworth North mine targets the seams of Foybrook and Burnamwood Formations. The coal seams extend from the shallow Broonie seams through the Bayswater, Lemington, Pikes Gully, Arties, Liddell and Barrett Seams.

Coal is extracted from eight seam groups. In stratigraphical order, those seams are the Broonies (BR1-10), the Bayswater (BAY1-2), the Upper Lemingtons (ULM1-9), the Lower Lemingtons (LLM1-12), the Pikes Gully (UPG1-5 and the LPG), the Arties (UAR1-4 and LAR1-2), the Liddell (ULD1-4, MLD1-2 and LLD1-3 and the Barrett (BAR1-8).The seams are divided into defined plies commonly separated by mudstone and to a lesser extent sandstone.

Ravensworth North is the active mine for Ravensworth Open Cut. It is approved to open cut mine utilising truck and shovel operations.

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 designated areas of the mine.

Each of the coal seams is cleaned and then loaded by excavator or front-end loader into trucks and transported to the run-of-mine facilities. From here the coal is conveyed to Ravensworth Coal Handling Preparation Plant (RCHPP) for processing before export. At times a small proportion of the coal is supplied to the AGL Macquarie power generation facilities.

The rehabilitation process includes the shaping of the overburden emplacement areas, ripping and rock raking, the placement or preparation of a sowing medium, installation of drainage structures, the application of seed varieties and the delineation of these areas to restrict access.

Key equipment associated with ROC includes:
- Shovels;
- Excavators;
- Dragline at Narama;
- Loaders;
- Trucks;
- Dozers;
- Graders; and
- Watercarts.

At Ravensworth Surface Operations, coal is hauled from the mining areas to the ROM pad and dump hopper via internal coal haul roads. The coal is crushed by rotary sizers before being transported by parallel conveyor belt systems to either the Ravensworth Coal Handling Preparation Plant for export, or to the Bayswater and Liddell Power stations for domestic power generation.

Ravensworth North:
Ravensworth North produces thermal and semi- soft coking coal with a majority of coal supplying the export markets and some domestic. The thermal coal product is highly volatile with strong combustion characteristics and has been widely used for power generation as well as for general industrial use. Semi-soft coking coal produced by Ravensworth North is used by steelmaking blast furnaces as a component in the coke blend. The semisoft coal is low in ash and sulphur with attractive coking properties.
