  • Industry Spotlight: Mining Aggressive Hydraulics

    10/25/2016· 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. Longwall miners can remove areas of coal as wide as
