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.
