    From 1960 underground mining used new techniques employing scraper loaders and a coal blasting system which shot coal off the coal face. By the late 1990s underground mining occurred at depths of 150-500m. The coal seam was reached by vertical shafts or sloping tunnels and coal was extracted using continuous miners or longwall equipment.
