The decision on whether to operate an above or underground mine is heavily influenced by a couple of important factors. The major factor in deciding on whether to go underground or open cut is the stripping ratio (Whittles et al. 2007).This is defined as the ratio of the volume of overburden (BCM) moved to the amount of coal produced (tonnes).

Overall when compared to other methods, opencut is much safer. Opencut mining is responsible for 65 percent of the raw coal production in New South Wales. Opencut is also a good method for gold and copper. Underground mining. Underground mining occurs underground through the creation of tunnels. These tunnels go deep into the mineral seam.

Openpit mining, also known as opencast or opencut mining and in larger contexts megamining, [1] is a surface mining technique of extracting rock or minerals from the earth from an openair pit, sometimes known as a borrow . This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.
