mines have one shaft
Slope, Drift and Shaft mines all exist in West Virginia.
it cant collapse in the way shft mines can. As Shaft mines are underground it makes it alot more easier for it to collapse on everyone and they will all die so therefore open pits are much much safer than shaft mins. Thanks
Drift mines are characterized by the use of a level tunnel leading into the mine, while slope mines have an inclined tunnel, and shaft mines utilize a vertical tunnel
No, not every mine had a shaft. Some mines used adits, which are horizontal tunnels dug into the side of a hill or mountain to access the mineral deposits underground. Adits were particularly common in hilly or mountainous regions where it was easier to dig horizontally than vertically.

Strip mines,Openpit mines & shaft mines
A horizontal shaft into a mine is called an adit. Adits are used for access to underground mines and are typically driven into the side of a hill or mountain.
The three types of mining -strip mining,open pit mining,and shaft mining

Open pit mining is generally cheaper than shaft mining because it requires less equipment and labor. In open pit mining, large quantities of ore can be extracted quickly and efficiently using heavy machinery. Also, open pit mines are typically less deep than shaft mines, which reduces the complexity and cost of excavation and support systems.
Slope mining is a method of accessing valuable geological material, such as coal. A sloping access shaft travels downwards towards the coal seam. Slope mines differ from shaft and drift mines, which access resources by tunneling straight down or horizontally, respectively.
