Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Opencast coal mining: process and method Opencast mining, a method of mining introduced in 1942 to maintain coal supplies du ring the Second World War, is a quarrying method that is viable where a coal seam is relatively near the land surface or where a pit can expose a number of seams within an acceptable depth (normally up to 100m in the UK).

This opencast mine has 2 areas in which mining is being done – ATCOM North and the South Pit triangle. The North area has No. 4 seam and No. 2 seam pillars which are mined by Dragline and truck and shovel operations. The overburden is removed down to the No. 4 coal seam which is then removed by a Company owned fleet.

When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when ...

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which ...
