Underground Mining 2012 - MineralsEd

Underground Mining 2012. Underground Mining. MineralsEd.ca. Underground mines are developed by excavating shafts (vertical) or adits(horizontal) to reach buried ore bodies. So‐called driftsare tunnels created by mining ore; stopesare vertical shafts created by mining ore. The surrounding waste rock is left behind.

It depends on the mining method used. For underground mines the mining rate is typically less than 20,000 tonnes per day (tpd); 10,000 tpd is a large capacity (and highly mechanized) underground mine. However, the block caving method can achieve mining rates much greater than 20,000 tpd.

Environmental Risks of 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.
