Open-Pit Mining Methods

Open-Pit Mining Methods. Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.

Open-pit mining – Open-pit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow. Mountaintop removal mining – Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintops. The mountaintop is removed by using explosives to break up layers of rock above the seam.

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.
