A common method of subsurface mining that is used to extract coal and salt is known as room-and-pillar mining. In coal mines, a network of entries, called rooms, are cut into a seam, a horizontal layer of coal. Between the rooms, pillars of coal are left standing to support the roof. When the mining of rooms is completed, the pillars are then ...

List of Pros of Strip Mining. 1. It is much more efficient compared to underground mining. Those who advocate for strip mining believe that the recovery rate of materials is higher using the method. It is estimated that about 80 to 90% of the material can be recovered compared to the 50% recovered using tunnel mining.

Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates. Disadvantages include its high visibility ...
