Mining | National Geographic Society

May 20, 2022The two major categories of modern mining include surface mining and underground mining. In surface mining, the ground is blasted so that ores near Earth's surface can be removed and carried to refineries to extract the minerals. Surface mining can be destructive to the surrounding landscape, leaving huge open pits behind.

Shrinkage stoping - QueensMineDesignWiki

Date: May 2010. Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the "working floor" and to support the walls. During the mining cycle, only 30 - 35% of the ore blasted is ...

Coal Mining - Methods of Extraction - Modern Surface Mining

Modern Surface Mining 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, or strip) mining methods. Open cast 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.
