Design and construct a 4.25m finished diameter lined shaft 186m deep. The ventilation shaft was constructed using blind boring and remote lining methods. The shaft was completed prior to the underground tunnels reaching the location of the shaft bottom. This enabled Dendrobium to have the ventilation fan ready to run when the mine development reached the shaft location. Works also included construction of access road and concrete works for the ventilation shaft.
The Dendrobium Mine is located within the environmentally sensitive Sydney Water Catchment area. Abergeldie fulfilled the specific environmental site requirements by employing comprehensive environmental control and monitoring systems.
