What Are the Different Ways That Minerals Can Be Mined

Mining is the process of mineral extraction from an ore or rock seam. The minerals can range from precious metals and iron to gemstones and quartz. In ancient times, miners recognized a mineral rock formation from its outcrop at the surface. Modern mining technology uses geophysical techniques that involve measuring

Digging deeper: Mining methods explained | Anglo American

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale 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.

Mining methods NSW Mining | The official NSW Minerals

When the mineral seam becomes exposed, it is drilled, fractured and the mineral recovered for processing. Open-cut mining can be more effective than underground methods, generally recovering 90% of a mineral deposit, and accounts for about 65% of raw coal production in NSW. Open-cut mining is also used for some gold and copper production in NSW.
