Before mining can commence the land needs to be cleared of timber and vegetation Alongside this process may be the collection of seeds andor saplings for inclusion in a seedbank which will form the basis of postmining revegetation of the site Next the top soil is removed and is usually also stored for replacement during rehabilitation...
