Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–6.0 m (2 ft 0 in – 19 ft 8 in) thick). The section of rock that is being mined, known as the longwall panel, is typically 3–4 km (1.9–2.5 mi) long, but can be up to 7.5 km (4.7 mi) long and 250–400 m (820–1,310 ft) wide.
The mine was opened in 1978 by BHP. Longwall mining was undertaken from the mine until May 2001, when the mine was shut down. Teralba Shaft No. 1 and Teralba Shaft No. 2 have been filled. A 4 MW Waste Coal Mine Gas (Methane) generator is at the site providing electricity into the grid.
Production from the mine peaked in the 1970s, when over 1,600 miners were employed at Parkside. On average, over 760,000 tonnes (840,000 tons) of coal was mined during this most productive time. [5] The deepest shaft was 882 yards (807 m), [6] and coal was mined using the longwall mining method. [7]
