Since the cost of removing the over burden is charged to the cost of mining, a point is reached, as the cover increases in thickness, beyond which open-cut mining does not pay and some method of underground mining must be used. Large deposits of copper and iron ores are worked by open cut mining, usually by the bench method.
Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente,in Chile, is the world's largest underground copper mine.

Underground mining is used to recover ores that are deeper into Earth’s surface. Miners blast and tunnel into rock to gain access to the ores. How underground mining is approached from above, below, or sideways depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding rock.

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 than on
