Aug 22, 2018· Impacts of underground mining. Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. This causes serious damage to buildings.
Mining operations release heavy metals that can be extracted by water. Depending on the mine and its location, Ni, V, Cr, Mn, Cu, Pb, Zn and As can be released into the hydrosphere. Mercury Mercury was widely used to in California gold mines to extract the precious metal from solid ore.
