Guide To Surface Mining: The Different Types & Tools Used
Blocks. Yet another important tool in the surface mining process is the block system. Many block systems rely on a welded-in construction that requires up to an hour and a half to change, but some manufacturers offer blocks that rely on modular construction instead — allowing for changes that can be made in as little as 15 minutes.
Mining and Refining – Process
Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
