Open Pit Mining TechniquesSurface MinesRock or Mineral

Open pit mining, also known as opencast mining, open cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

Strip Mining vs Open pit mining mining

Strip mining is for shallow, mostly horizontal deposits, usually extended over a considerable area. You remove the overburden, take the ore/coal and move another step in. Behind you, land reclamation can begin relatively soon. As such, the 'mine' moves across the land over time. Open pits are for deposits that are tilted or even vertical.

Stoping Mining Methods

Mining by Sublevel Caving. In sublevel caving, relatively thin blocks of ore are caused to cave by successively undermining small panels. The ore body is developed by a series of sublevels usually spaced at vertical intervals of 18 to 25 or 30 feet (more recently, intervals of 50

Strip Mining vs Open pit mining mining

Open pits are for deposits that are tilted or even vertical. Extraction is limited to a relatively smaller area, and the mining operation moves down over time. To dig deeper, the pit also has to be widened over time, increasing the ratio of overburdenore. Eventually, you will have to remove so much overburden that extraction no longer is profitable.

Surface mining

Surface mining, including strip mining, open pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

What are the main methods of mining? American

There are four main mining methods underground, open surface (pit), placer, and in situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
