Everything You Need To Know About Underground Mining

Nov 03, 2018· Underground Mining It is one of humanity's oldest and most impressive engineering activities, extracting an ore or mineral from many hundreds of feet deep undergroundFrom the days of laborers toiling deep inside narrow, rickety and illsupported tunnels using crude pickaxes and with only candlelight to guide them in their quest for gold, silver, copper or other precious materials

Underground Mining Geology Mineral Processing & Metallurgy

In the previous topic we learned that the economics of mining is particularly related to the amount of ore that can be produced and the amount of waste rock that must be moved That makes underground mining particularly suited to structurally compact ore bodies with high grade ores which don’t require an extensive network of access tunnels through worthless rock and which don’t involve

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground

How Underground Mining Works | HowStuffWorks

Underground mines are the alternative to surface mines Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers]Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or
