12 Mining methods and method selection
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

Types of Surface Mining | American Mine Services
Surface mining is often the preference for mining companies. This is because removing the terrain surface, or overburden, to access the mineral beneath is often more cost-effective than gouging tunnels and subterranean shafts to access minerals underground. This method is often considered safer, as well, and doesn…

Different Types of Mining | 4 Types of Mining
The following will share core information on some of the most common types of mining methods. Surface Mining. Surface mining is a process where ore is extracted from the ground by digging it out with heavy machinery. The ore is then transported away from the mine site. This can be done either by truck or rail.
