The mining industry plays a vital role in Australia's economy, with the country being one of the world's leading producers of various minerals, including coal, gold, and iron ore. To maximize efficiency and safety in mining operations, it is crucial to understand the essential equipment used in Australian mines.
Room-and-pillar mines allow for continuous mining. This process uses robotic equipment to move vast amounts of coal quickly. Longwall mining mines a single coal seam in one single tunnel, rather than the many rooms used in the room-and-pillar technique. Contour mining is similar to longwall mining, but it follows the contour of a …
