INDIAN GEOGRAPHY

Detailed explanation-1: -Shaft mining, or shaft sinking, involves driving vertical shafts into the earth. Once a desired depth is reached, auxiliary tunnels, or drifts, are dug in all directions to access ore and mineral deposits. Shaft mines are dug when there are concentrated mineral deposits embedded deep underground.

Detailed explanation-2: -Click each image to learn about some methods of subsurface mining. Shaft mining is the deepest form of underground mining. It involves excavating a tunnel from the top to the bottom area of the mine. From this tunnel, the miners then dig long horizontal tunnels to get to the coal or other mineral ore.

Detailed explanation-3: -Definition. Mining beneath the surface of the earth.

Detailed explanation-4: -Most underground mines have 3 shafts (rock shaft, service shaft and the ventilation one) and if something ever happens to any shaft the production can be severely disrupted and consequently the mine may suffer serious financial losses.
