Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as quot;the conveyor methodquot; of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was an electric cutter to
Belt conveyors consist of two powered pulleys with a continuous loop of belting material used to convey products. Belt conveyors are the most economical powered conveyor and are typically used for conveying products over long distances, at high speeds, or for incline/decline applications. This is
