  • Shaft Mining Mining Techniques Underground Mining

    Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron coal etc. which can be found at the depth of the earth s surface. It is found mostly all over the world.
