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.
A mining method for narrow orebodies where no backfill is required during the stoping operation. Successive horizontal slices of ore are taken along the length of the stope back and left in place to support the walls rocks and serves as a working floor for the next slice. Ore is drawn from drawpoints at the bottom of the mine.
