Coal properties vary depending on how much carbon is in the coal (coal rank). Black coal is so called because of its colour; it varies from having a bright, shiny lustre to being very dull, and from being relatively hard to soft. The term 'black coal' is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals.

1972) were conducted on hard, strong rocks, and found that relationship between UCS and the point load strength could be expressed as: UCS = (K) Is50 = 24 Is50 (2) Where K is the "conversion factor." Subsequent studies found that K=24 was not as universal as had been hoped, and that instead there appeared to be a broad range of conversion factors.
