Environmental Risks of Mining

Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves largescale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.

Causes and Mitigation of Corrosion on Buried Copper</h3>IntroductionMitigationConclusionCopper is usually immune to the effects of corrosion caused by contact with most soils. This is because a naturally protective reddishbrown (cuprous oxide) coating forms on copper. In most soil conditions, this protective coating remains in tact or, if damaged, is easily regenerated. However, the following conditions will destroy this coating and prevent it from regenerating
