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.

Coal wastes: handling, pollution, impacts, and utilization

During the coal mining process, a significant amount of coal wastes is produced, including (1) mining wastes, (2) washery wastes, and (3) secondary processing wastes. Since 2017, the annual global CMWs are estimated to be 315 million tons for underground coal mining. This results in the disposal of a considerable volume of wastes at waste dumps.
