Coils, probably woven wire cable used for tramways to transport ore and supplies.
Steel, could be corrugated sheets used for roofing and siding. Steel beams maybe used in a few buildings? Some mines did used heavy Steel sheets laid on tunnel floors before blasting for easier mechanized clean up (but when?).
