Largescale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significant developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and operating at higher stripping ratios (Westcott et al., 2009).

WhatsApp: +86 18203695377Opencut mining or surface mining is a technique used to extract ore located close to the surface and is the most common method of mining. Opencut mines are used when deposits of commercially useful minerals or rock are found near the surface and where the overburden (surface material covering the valuable deposit) is relatively thin or structurally unsuitable for tunneling.

Opencut mining causes complete disruption of landforms and soils, which can impede or prevent the restoration of original or other preexisting ecosystems because ".essential properties of the original soils cannot immediately or easily be reinstated" (Ngugi et al., 2018, p. 839).However, the postmining outcome should also be contingent on preexisting landuse.
