Surface mining purposely exhumes ores at the surface or close to the earth's surface, including open-pit mining and dredging. Underground mining, however, removes minerals such as in hard-rock mining by extracting under the surface and removing the ore (Aryee et al., 2003; Balasubramanian, 2017; Gibria, 2014; Northey et al., 2013).
