New longwall plow system achieves high production at low coal seam

Mining Engineering , 2015, Vol. 67, No. 3, pp. 49-49


Caterpillar has developed the Cat GH800B longwall plow system, designed for mining very low coal seams at high rates. Building on the attributes of the proven GH1600 plow system, the Caterpillar longwall team in Lünen, Germany, worked with the German Ibbenbüren Mine to design and construct a system for mining an anthracite seam averaging only 0.85 m (33.5 in.) thick. The result is the GH800B plow and associated longwall system, which is now operating in the Ibbenbüren Mine — where the seam does not exceed 1 m (39 in.) in height.
