Terrace mining is similar to open-pit mining as a large hole of about 12 meters is dug here too. In the terrace-mining method, steps or "benches" are created parallel to the pit on the way to the bottom. These benches can be used as exploration spots, where miners search for emerald-rich rock, or they can be used to move away waste rock. This method is used for emerald extraction in Colombia ...
