Key infrastructure activities included constructing a new mine office and bath house facilities, conveyors, coal stockpile, train loading structures including a concrete rill tower, buildings and general infrastructure works, plus refurbishment works.
  • To allow access to coal seams, Walter excavated two tunnels from the environmentally sensitive Illawarra escarpment plus a further 20 kilometres of underground roadway.
  • The works included design and construction of six underground and surface conveyor systems.

North Goonyella Coal Mine, Qld

  • Walter's initial work at the North Goonyella Coal mine in Central Queensland involved mains driveage work and the installing secondary support to underground roadways.
  • Our mining operations have since been retained to carry out a diverse range of underground services at the mine.
