What is open-cut mining? - Oresome Resources

Open-cut mining is used when the minerals are found over a large area and relatively close to the surface. The open cut mine is dug downwards in benches or steps which slope towards the centre of the pit. To uncover the minerals the land is first cleared of vegetation as when a new building like a house, school, factory or shop is constructed but in the case of open-cut mining, the top soil is removed and stockpiled for later use in the rehabilitation process.

20-12-2013· Open-cut coal mining began in central Queensland's Bowen Basin approximately 50 years ago. Over this period of time, mine rehabilitators have used a variety of tree, shrub, and groundcover species to create 'novel ecosystems' to stabilise soils and provide vegetative cover for pre-supposed final end-land uses. We examine post-mining rehabilitation from multiple soil and …
