The waste, filth, and rock that they take off of the top of the next strip is put on top of the last one. This is recurring until the last strip is done and the waste from the primary strip is brought back to fill it. Strip mining, like other types of surface mining, finishes in hurting the area around the mine.

Oct 12, 2016  Mining is broadly categorized into two types: surface and subsurface. Removes materials close to Earth’s surface. Open Pit: Removes materials from an open pit. Used when tunnels may not be stable or overburden is very thin. Strip Mining: Uses shallow pits for removing building materials. Leaves spoil banks until the area is reclaimed.

There are three common surface mining methods. Strip mining. Strip mining is the activity of removing a layer of earth to access the minerals that are in shallow deposits and continuing to do the same in adjacent areas without digging deeper vertically. Strip mining is best suited for shallow and horizontally located deposits.

Nov 13, 2020  Surface Mining Methods Strip Mining. When resources are available close to the surface, a strip mine is the most efficient method of extraction. The layers of regolith covering the resource are taken away, and the exposed ore is mined. This method is also called open-pit mining, or regolith harvesting, depending on the depth of the work.
