  • Longwall Mining

    Longwall mining is a high extraction technique where coal is removed in 1,400 ft. panels that stretch for miles. Unlike traditional room and pillar mining, in a longwall mine no coal pillars are left in place to provide surface support above the panel. Hydraulic supports are used to hold the roof up at the working face of the coal seam.
