Lets see...
Construction: Like building storage sheds, office buildings, crew facilities.
Moving dirt: Like building adits for mines, pads for leaching, crushing and stacking ore, roads.
Manufacturing: Like building trommels, shaker tables, water trucks, stamping mills, Merrill Crowe circuits.
Nope, nothing useful in mining. Course I've left out a few things, but its all just moving dirt, construction and manufacturing.
