Highwall mining is a hybrid of surface and underground mining technologies that is used to recover coal that is otherwise uneconomical due to:

  • Increasing open – cut strip ratios
  • Reaching pit limits with available coal in the barrier pillars
  • Protected surface features (e.g. rivers, streams, archaeology)
  • Inadequate panel length for a punch long wall
  • Mining end walls in allocated reserves in conjunction with conventional surface methods
  • Orphan deposits where available resources does not justify capex due to quantum or structure
  • Deposits in agricultural areas.
