The risk of skin disease for miners may be linked directly to the special characteristics of the resources being worn, but it may also depend on the applied working method, which is often very similar in modern tunneling and in mining. Accelerators (in shotcrete) and reactive resins (e.g., epoxy resins and polyacrylates) represent a particular hazard to the skin of miners; in contrast, the content of chromate in cement has decreased in many countries. Occasionally rubber additives, explosives, and lubricants are the reason for skin problems. In mining depending on the type and methods, nickel, cobalt, mercury, and other metals as well as xanthates should be taken into consideration as relevant allergens.
