Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. ...
The room and pillar method is often used to mine smaller coal blocks or thin seams, and seam recovery ranges from 35% to 70%, with higher seam recovery rates applicable where retreat mining is combined with room and pillar mining. The other underground mining method commonly used in the United States is the longwall mining method.

Underground mining accounts for 60% of world coal production, but is less common in NSW, making up around 35% of raw coal production. This method is also used to mine metallic minerals like gold and copper. The two main types of underground mining in NSW are bordandpillar and longwall mining.
Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 180 ft (55 m), are usually surface mined.
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 .
As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn''t require tunnelling into the earth and is a simple method of mining that yields high ...
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped.
