What Are the Different Types of Mining? Reference

Most surface mines only extend to about 650 feet, after which the underground mining method is used. Room and pillar is a method of underground mining that involves excavating rooms with pillars that hold up the roof and is used for shallow mines. In block caving, miners drill tunnels underneath the ore deposits and then draw the material down.
