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.

South32 longwall change improves Illawarra output
South32 has improved metallurgical coal production at the Illawarra metallurgical coal operation in New South Wales after returning the site to a three longwall configuration. Illawarra which is
Whitehaven slashes production at NSW mines Australian Mining

Improving safety and productivity in coal mines CSIRO
Around 90 per cent of Australia 39s underground coal production comes from longwall mining. Traditionally a mechanical shearer cuts along the coal seam beneath a roof supported by hydraulic jacks exposing miners to multiple risks. Increasing safety and productivity in longwall mining has been a longterm industry goal.
