Mine Safety amp; Health Act Explained. Because the mining industry creates dangerous working conditions, both new miners and current miners are required by OSHA to complete specialized safety training to instruct them on how to recognize health and safety hazards, minimize accidents and injuries, and protect themselves in hazardous and emergency situations.
In coal mines, the most common means of fire warning are shutdown of electric power and subsequent notification by telephone and messengers. This is not an option for noncoal mines, where so little equipment is powered electrically. Stench warning is a common method of emergency communication in noncoal underground mines (Pomroy and Muldoon

Heres a checklist of reminders to consider when reevaluating your safety program for an underground mine. Illumination For general tunneling operations, the MHSA requires a minimum illumination intensity of 5 footcandles, although 10 footcandles must be provided for shaft heading during drilling, mucking and scaling. Check all lamps regularly.
