2 – Mining Hazards. Writings mention common risks to deep-vein miners and their observations of the effects. For example, Pliny writes, "when well shafts have been sunk deep, fumes of sulfur and alum rush up to meet the diggers and kill them" and "The fumes from silver mines are harmful to all animals" (Duncan, 1999). 3 issues were challenging in particular: lack of ...
