Environmental Risks of 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 airEnvironmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes These processes also have an impact on the atmosphere from the emissions of carbon which haveEnvironmental impact of mining Wikipedia
Traditional mining Wikipedia
Traditional mining, also known as oldschool mining, is a mining method involving the use of simple manual tools, such as shovels, pickaxes, hammers, chisels and pans It is done in both surface and underground environments Until the early 1900s, traditional miningMining, process of extracting useful minerals from the surface of the Earth, including the seas A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure (One organicMining | Britannica
