The Difference Between Underground Mining And Surface Mining

The process of removal of essential mineral ores or geological substances from soil or sand is called mining. These minerals are of great value and are abundantly available in rocks and earth’s surface. Minerals can be metallic or non metallic and can be used for a several of purposes. 

Mining is conducted basically in two ways, either underground, or surface mining. Surface mines, or strip mines, are large pits where dirt and rock are removed to expose the minerals. Underground mines are large tunnels that are dug deep into the ground to reach minerals that are too far underground to be reached from surface mines.

Surface mining can be done on mountain tops or on surface of the beaches. The surface of the beach is rich with heavy minerals. Heavy mineral mining is carried out extensively in Kerala and Tamil Nadu. One of the leading companies that undertake heavy mineral mining is VV Mineral. VV Minerals India manufactures mainly four minerals i.e. Rutile, ilmenite, Zircon and Garnet. 

Underground mining is done mainly for minerals that are embedded deep in the soil, for example coal. Coal mining is a very economically beneficial activity and contributes greatly to the economy of our country.
