These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.

Different mining methods are designed to produce different types and magnitudes of displacements, in the near-field and far-field domains of an orebody. For example, the mining method illustrated schematically in Figure 12.2 is designed to restrict rock displacements in both the near field and the far field of the orebody to elastic orders
