Australia's top two coal mines each produced about 20 million tonnes of coal last year. The Benefits of Open Cut Mining According to Geoscience Australia, an open-cut coal mine can be a safer and more efficient way of extracting coal. This increased efficiency is because up to 90 per cent of the resource is able to be extracted at the seam.

7.2.1: Open Pit Mining. Open pit mining almost always applies to non-coal materials, mostly metal and aggregate mining. However, near-surface steeply dipping coal seams are extracted using open pit mining. Reclamation, i.e., returning the land to an acceptable standard of productive use of the open pit mine is deferred until the mine closes.

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.
