Strip Mining A Destructive Way of Coal Extraction

The process of strip mining also lowers groundwater levels around the mine. In order to remove the coal, vast quantities of groundwater are pumped out of the mine and as a result, surrounding ecosystems and farmland may become drier, and erosion may start to change the landscape. Strip mining also uses significant amount of water to suppress dust.

Coal Geology Geoscience Australia

Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.
