Coal mining - Underground mining Britannica

Mining methods. Modern underground coal-mining methods can be classified into four distinct categories: room-and-pillar, longwall, shortwall, and thick-seam. Room-and-pillar mining. In this method, a number of parallel entries are driven into the coal seam. The entries are connected at intervals by wider entries, called rooms, that are cut through the seam at right angles to the entries. The resulting grid

Here are the Types of Underground Mining and Their ...

Depending on how these ores are extracted, mining methods can be categorized as ‘surface’ or ‘underground’ types. In surface mining, the rock barrier on top of the deposit is removed to access the ore. However, sometimes, such deposits occur too far below to access them from the surface. In such cases, they are extracted by leaving the overlying rock intact, and accessing the deposit ...

How Underground Mining Works HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Types of Drilling Methods used in Mining Boring

IV. Underground Drilling: To drill a hole from underground workings for purposes of prospecting, stowing, tapping water or gas or any other object, the drill equipment has necessarily to be of smaller dimensions. This restricts the size and weight of the machine and therefore puts limitations on the size of the bore hole and its length (or depth).

mining (see Table 1). Mining methods for narrow vein deposits are highly selective mining methods and tend to be unproductive, while highly productive mining methods are unselective, and result in an increase in unwanted dilution. Often the adoption of a more highly productive mining method is precluded by the inherent decrease in head grade delivered by the method through this increased dilution. However, bulk mining methods can lower the cost of mining
