open pit mining and strip mining

What is the difference between strip mining and open pit ...

2020-1-7  Strip Mining vs Open pit 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. Open pits are for deposits that are tilted or even vertical.

Open Pit Mining - an overview ScienceDirect Topics

Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.

2021-7-15  Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining.

2021-7-15  Open Pit Mining. 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 - an overview ScienceDirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

2021-10-21  Open Pit Mining. Open pit mining is similar to area mining. The technique is common in the western United States (and other parts of the world) where very thick — 50 to 100 foot — coal seams exist. Open pit mines are usually large operations. Production levels may exceed 10 million tons of coal per year.. The thick coal seams found at these large mines ensure that the amount of land ...
