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.

What Is a Mine Shaft? | An Underground Miner
Horizontal tunnels, called drifts, are used for drainage in shaft mining. These drifts form an important part of the structure. Without proper drainage, water can well up inside the mine and damage the mining components and equipment. The place where a shaft meets the main ore body is called the shaft station, inset, or plat.

TBMs in Mining
Robbins' close partnership with the mining industry spans decades, from non-circular prototype machines such as the Mobile Miner to early TBM usage in coal, copper, and gold mines worldwide. While those early machines were successful, modern machines are vastly more powerful and efficient than those tested and used in the 1970s and 1980s.
