One way to mine emeralds is through the open-pit method. Workers dig a large pit of about 12 meters deep and then blast the surface with water to disclose the mineral-bearing rocks. In the open-pit mining method, a lot of waste rock must be moved away. The mining area is literally shaped like a pit that can hold equipment and workers.
