Open Cut or Underground Mining – Which is better?

2017-10-21  Open-cut is also a good method for gold and copper. Underground mining. Underground mining occurs underground through the creation of tunnels. These tunnels go deep into the mineral seam. This can be in excess of hundreds of metres. Tunnels are necessary to move equipment into the mineral zone. Coal is the largest portion of underground mining.
