Longwall Mining Method and Design - 911metallurgist

Historically, room-and-pillar mining has dominated coal production, and this mining method has been the focus of most multiple-seam research. Advances in Longwall Mining Method have made this system more economically attractive because of its efficiency and production potential. The high productivity being achieved by longwall mining demonstrates its potential for being a substantial segment of

Longwall Mining Overview | Introduction | underground COAL

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.

Longwall mining - Wikipedia

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6 – 1.0 m thick). The longwall panel (the block of coal that is being mined) is typically 3 – 4 km long and 250 – 400 m wide.
