How do the strip mines deal with the pitch? The only thing I can think of is serious stair stepping?

The other thing may be smaller shovels. Sorry for the one-up-manship but those are small stripping shovels

I would think that if they are opening a narrow trench across the pitch ( same as a cross cut underground ) that a dragline would work well. Draglines can move the spoil farther that a shovel. One issue with a dragline is the spoil would be unstable if placed up slope.
