Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground. ...

Coal in the seam is then excavated. Surveyors are present to ensure the coal is mined optimally. The coal is blasted into smaller layers, which are dug up and transported by trucks to a processing plant. Throughout the coal mining process, we minimise the impacts on the environment including the air and water quality, noise and heritage sites.

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.
