There are overall, many different types of mining
However, 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.
Other types of mining do not require as steep of an incline or a lift of some sort. Shaft mining is the process where miners dig straight down, or almost straight down, until they reach their desired depth. Then the mine begins to branch out in all directions. Miners will enter or exit a mine through a lift or elevator installed where the initial vertical tunnel was originally.
