Deep Shaft Mining is two tunnels going deep underground, on tunnel for the miners to come up and down and the other for the coal to be lifted up to the ground.
shaft
Deep mining of any kind is done in tunnels leading off a vertical shaft into the ground, as opposed to 'open pit' or 'strip' mining. Deep mining is principally done for copper.

in open cast miniing the earth surface is simly dug out to take minerals which are shallow.in shaft mining we should put bores to take minerals which are deep under the earth
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.
About 60% of the world's coal is mined via deep shaft extraction. The other 40% is recovered by one of three surface mining techniques: area mining, contour mining, mountain top removal mining.
The types of mining are shaft mining, strip mining, surface mining, and subsurface mining.
