Jul 21, 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.

The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
