The ore-to-overburden ratio for surface mining is generally around 1:5 to 1:2 depending on local situations (Feng et al., 2021, Yellishetty et al., 2008). In 2008 and 2009, about 75 % of overburden materials and 25 % of tailings were generated as solid residues in Minas Gerais, Brazil (Schatzmayr Welp Sá et al., 2022).

The primary solid waste product of surface coal mining is overburden (also known as spoil), the material that is moved to access the underlying coal seams. Once removed, this material is generally stored in large (>100 m in height) piles until it is re-contoured in preparation for post-mining rehabilitation, often remaining there for decades.

Overburden refers solely to the material removed from above the first deposit or seam of valuable material. The term interburden is then applied to anything found below that deposit but above further deposits. Even if the two materials are different, such as ore above coal, the rock and sand between them will be referred to as the interburden.
