Types of Mining Methods Cummins Inc.

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.

The Four Main Methods of Mining OreFlow

2019-12-4  Strip mining is done only when the ore body is in close proximity to the surface. 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.

2020-3-12  Using specialized machines, longwall mining is an underground mining method that cuts out panels of the coal, which are then sheared down and brought to the surface. This method is highly mechanized, and is therefore a very safe type of mining. It is a highly productive method as well, with a very low cost per ton as compared to some other methods.
