Mining Methods In Copper Mining
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
Copper Mining and Processing: Life Cycle of a Mine
Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.

Deep underground mining methods, planning and optimisation. Underground mining methods have evolved from primitive handheld hammer and chisel to modern automated and mechanised mining. As the exploitation of deep mineral deposits gains prevalence, it is reasonable that mining methods will continue to evolve.
Risks to Human Health from Sulfide-Ore Copper Mining
The human health impact of proposed sulfide-ore copper mines must be fully evaluated to prevent creating major threats to public health. Sulfide-ore copper mining has the potential to release numerous chemicals known to negatively affect human health, including mercury, arsenic, lead, asbestos-like fibers, and air pollution.
