Oct 25, 2016 Longwall mining is a highly productive coal mining technique. These machines consist of multiple coal sheers mounted on self-advancing hydraulic ceiling supports. Longwall mining machines are massive, about 800 feet in width and 5-10 feet tall. The massive shearers cut coal from the wall face, allowing it to fall to a conveyor belt for removal.
The earliest attempts at hydraulic mining involved transporting coal from the mine mouth to the nearest road or rail transport. For example, in 1924 a flume (water race used for carrying coal) was constructed from the mouth of the Cardiff Bridge mine to the railway at Seddonville, a distance of 1.6 km.
