The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Mining. In Australia, nearly 80% of coal is produced from open-cut mines, in contrast to the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of …

The first step in the process of generating electricity from coal is to mine it. Coal is typically found in underground mines or in open-pit mines. The coal is extracted using large machinery, such as draglines and shovels. Once the coal is mined, it is transported to a power plant via truck, train, or conveyor belt. Step 2: Transportation and ...
