Mining Wikipedia

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

Underground Mining, Underground Mining Equipment

Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.

Underground Mining Methods – EXCELLENCE IN

21/07/2016· Underground mining is the process of extracting minerals and ores that are located too far underground to be mined efficiently using surface mining methods. The primary objective of underground mining is to extract ore safely and economically while minimizing handling of waste rock. Typically, underground mine has less environmental impact.

What Are The Primary Methods of Underground Mining?

21/05/2019· Primary Methods of Underground Mining . Sub Level Caving: It is currently one of the most innovative mining methods in the industry. This method of mining is usually implemented when it is no longer viable to mine in an open mine. The procedure involves drilling vertically downwards directly into the ore. This is followed by drilling sub levels
