Answer 5

The common terms are surface mining (aka open cast mining) and sub-surface (aka shaft mining or underground mining). There is also drift mining. Opencast is finding what you want on the surface - or very close to it - and digging it out. This is how, for instance, we get gravel pits. Underground mining - very commonly used to get coal - involves digging a vertical shaft down into the ground until a seam of desired material is reached. Then one digs along the seam horizontally and the material is winched back up the shaft to the surface. Drift mining is done where the seam comes out of the side of a hill and so it is reachable without a shaft being necessary.

Answer 6

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
