Read More2019-6-30 Why mining is done so deep in the ground? Underground mining is used for ores that are deep in Earth’s surface. For deep ore deposits, it can be too expensive to remove all of the rocks above the ore. These methods are more expensive than surface mining because tunnels are made in the rock so that miners and equipment can get to the ore.
