Dartbrook Mine Overview

Filed in Recent News by April 8, 2019

AUSTRALIAN Pacific Coal, the owners of the underground Dartbrook coal mine, located approximately four kilometres west of Aberdeen, are considering challenging a decision made by the Independent Planning Commission not to grant a licence extension for the mine.

In August, the Independent Planning Commission approved modifications to restart the mine using bord-and-pillar methods instead of longwall mining and make changes to their coal delivery and handling, but refused to extend the mining licence for five years.

The Company has until November 8 to lodge an appeal with the NSW Land and Environment Court.
