Project Description: Narrabri underground coal mine is located 28 km south of the Gunnedah Basin in New South Wales and produces high energy export grade thermal coal.

Mastermyne were engaged at the Narrabri Mine to upgrade the existing ventilation circuit in the underground main headings to provide additional return air roadways.

The upgrade consisted of adding a return roadway along “B” heading to the existing glancing returns in “A” heading and “G” heading. This work was completed through 3 separate portions of work.

1.     Portion 1 to incorporate “B” heading as a return roadway between 22c/t and 47c/t Mains.

  • 4 x machine doors sets (2 x air locks)
  • 13 x 35kPa rated stoppings
  • 5 x 35kPa rated stoppings to form air locks
  • Clean up and removal of all superseded ventilation control devices.

2.     Portion 2 to create a line of overcasts at 47 c/t and incorporate “F” heading as a return between 47c/t and 51c/t Mains.

  • 2 x 35kPa rated stoppings
  • 1 x 35kPa rated oversize stopping
  • 1 x 35kPa rated air lock
  • 2 x machine door sets (1 x air lock)
  • 3 x 35kPa rated overcasts (including excavation of 1 x overcast site)
