Overview of Operation

Bengalla is a single pit open cut mine, using a dragline, truck and excavator method. The mine’s employees work in shifts to keep the mine operational 24 hours a day, seven days a week.

Geologically the operation is situated in a Permian basin called the Sydney basin, and mines the Whittingham Coal Measures of the Hunter Coalfields.

In 2015 Bengalla produced 8.318 million tonnes of thermal coal. After washing and preparation for sale, the coal is loaded onto trains and transported to the Port Waratah Coal Terminal in Newcastle where it is shipped to international customers.

Bengalla had JORC run of mine coal reserves totalling 269 million tonnes (163 million tonnes proved and 106 million tonnes probable) as at 31 December 2014.

Projects – Water Management Relocation (Stage 3 Dry Creek Relocation)

The initial stages of the Dry Creek Relocation project have been completed (construction of a clean water dam CW1 north of Wybong Road, pump station/ pipeline to direct water around the mine to return the dam to an empty state, and a contour levee west of mining operations to intercept clean water runoff and deliver it under gravity downstream of the mine).

The final stage of the Dry Creek Relocation project is due to commence early 2018. This water management project is required to allow Bengalla to continue mining westward whilst having sufficient mine water storage for operations to continue as per Bengalla’s SSD-5170.

The water management relocation project comprises:

  • Relocation of Bengalla’s main mine water dam west of Bengalla Link Road (DW1)
  • New raw water dam and washery dam adjacent to DW1
  • Pipelines and pumps integrating water management between the dams and site infrastructure
