  • Feasibility of high recovery highwall mining equipment

    Punch mining, longwall and shortwall technologies and the push-button miner all attempted to economically remine areas, with very little success. The Thin Seam Miner, more » on the other hand, not only recovers 80-85% of the coal in place to depths of 220 feet, but is environmentally sound, economically feasible, safe, and adapted to mine under all the seam conditions and grades of coal

    Pre-Feasibility Study for Highwall Mining at Curragh North

    01-01-2004· The primary focus for this thesis is to investigate the feasibility of highwall mining operations at the Curragh North mine. Highwall mining is best defined as the method whereby underground coal is directly extracted from the coal seam of an open cut highwall in a surface controlled operation by making repeated entries or drives into the seam.

    Design Programs for Highwall Mining Operations

    Highwall mining is a hybrid of surface mining and underground mining methods, and is often the only feasible method to recover the coal reserves in the central Appalachian coalfields due to the steep terrain and the closely spaced multiple thin coal seams.
