The disadvantages of mining iron
The tools that are used in shaft mining are a cradle, a windlass, a bucket and a pick.shovels, carbide lamps, tipples, mules and ponies.
There are some technological methods that are used in mining are:Open-cast mining : Open-cast mining is done when a mineral is located very close to the surface. In the open-cast mining, different minerals are taken out by removing the surface layer. Open-cast mining is famous for coal mining in India and many other countries.Shaft mining : The word 'shaft' refers to deep bores. In the shaft mining, deep bores are created to reach mineral deposits. This is because, these deposits lie at great depths. Petroleum and natural gas are extracted by shaft mining.

Shaft mining or shaft sinking refers to the method of excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.

Shaft mining is the earnest form of underground mining. Underground mining is selected when the rock or mineral is so far to reach using surface mining. Shaft mining is the kind of mine that you normally see in movies where the miner travels straight down into a profound, dark tunnel until he reaches the base. The shaft mine has a vertical man shaft, a tunnel where the men travel up and down in an elevator. Equipment is taken into the mine using this shaft, too. Short tunnels to the ore are dug from that man shaft. When the ore is dynamited and broken into chunks, it is taken to the top and loaded into trucks through a second shaft. There is usually an air shaft that gives the mine ventilation. When we visited a coal mine, it was amazing how much air moved around in the tunnels. Moving air removes the gases that occur naturally underground.
They all involve the mechanized removal of rock.
