Mining: The process of taking out minerals buried under the rocks is called mining. There are two main methods of mining, viz. open-cast mining and shaft mining .
Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process.
Shaft Mining: When deep bores (called shafts) are made to reach the mineral deposits at great depth, the process is called shaft mining.
