    Environmental Risks of Mining

    Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large scale 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.
