Mining Methods | SpringerLink

A brief description of the most common mining methods is provided in this chapter together with the main terms used by mine personnel, illustrating them with photos and diagrams. Description is limited to an introductory level and uses a basic lexicon which will be understandable for the junior mine geologists.

Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised ...

MINING METHODS |authorSTREAM

Underground Mining: There are two main methods of extracting coal by underground mining: room-and-pillar (or, bord -and-pillar) and longwall mining. Room-and-pillar minin g involves cutting a network of 'rooms' or panels into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine.

LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face....
