The Ewington Coalmine is a proposed open cut coal mining operation which is on the same large scale as the Muja mining operation. The mining method would follow the practices being employed at the Chicken Creek open cut operation near Muja in the Collie Coal Basin. This involves an open cut, strip mining operation using a dragline.
The Collie Basin is a depression within the Archaean basement containing Permian coal-bearing sediments. The Basin covers an area of approximately 274km2 and supports a variety of land uses other than coal mining, such as agriculture, hardwood mining, pine plantations, wildflower harvesting, seed collection, agriculture, power production, tourism, quarrying and recreation.
