Surface Mining, Industry of Metals, Minerals, Precious

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surfaceUnderground mining is used for gold, platinum, zinc, lead, and increasingly, coal As can be seen, surface mining is much more advantageous than its counterpart However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by undergroundThe Actual Difference Between Surface and Underground Mining
