  • Longwall mining Wikipedia

    Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" 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

  • The economics of extended pre-strip stripping

    A major operation in the recovery of any coal seam by surface mining methods is the removal of the overburden (Fidler, 1979). Of the available surface mining methods, strip mining is arguably the most common method used to mine coal in Australia. Pre-strip by definition is the removal of any waste material not considered to be valuable. In

    The majority of open pit mines in Australia currently operate using discontinuous shovel/truck systems. These systems are favoured as they enable; (i) mining capacity to be progressively scaled up over the life of a mine; (ii) the use of narrow benches that defer the high costs of stripping, and (iii) flexibility to rapidly adapt mine plans in the face of uncertainties caused by changing
