Bulga Open Cut continued mining coal reserves from the Bulga Pit, Southern Extension Pit and East Pit. In the Bulga and Southern Extension Pits, mining progressed in a westerly direction. Overburden was placed mainly in the Noise and Visual Bund and in-pit dumps.

Mining in the East Pit continued progressing to the south. Overburden from the East Pit was mostly placed in the Eastern Emplacement Area dump, with some placed in the Noise and Visual Bund.

Overburden was stripped using a dragline and a truck/shovel fleet. Coal was mined by a fleet of excavators and trucks. ROM coal was transported by dump truck via an overpass on Broke Road to the ROM coal hopper.

Once mined, the coal is transported to the Coal Handling and Preparation Plant where the minor waste component, usually clay or sandstone, is washed away. The waste is either disposed into tailings dams or thickened and co-disposed in the overburden dumps.

The coal is broken down to particles of less than 125 millimetres in a crusher and then washed, screened, rinsed and dewatered.
The product coal handling facilities include dual product conveying systems from the plant out to the stockpiles.
The CHPP can produce two streams of product coal; semi-soft coking coal and thermal coal.
