In the first five years of longwall mining at Pacific Colliery, special techniques of goaf sealing, gas drainage, goaf edge ventilation and goaf sampling were developed and used to o crcome the concurrent problems of spontaneous combustion and high methane emissions. The English-inspired back-return face ventilation system was modified to suit Australian mining methods and was first used as part of a 'Y' ventilation system and more recently was used with a 'U' system of ventilation. In conjunction with this ventilation system, the maintenance of a sealed goaf area was an essential element in the control of the spontaneous combustion in the goaf.
