Title New lighting regulations to spark improved safety production for coal mines.
Bibliographic information May 1976, Vol.81, No.5, p.79-87. Illus.
Abstract The mine lighting regulations issued by the Mining Enforcement and Safety Administration (USA) in April 1976 above all concern mechanised workplaces in underground coal mines and their hazards. Increased productivity is also expected from improved lighting. The surfaces designated must be illuminated to 0.06fL whenever self-propelled mining equipment is operated, e.g. continuous miners, coal-loading machines, cutting machines, roof-bolting machines. Other requirements concern voltage limitations for light fixtures and their earthing. The choice of footLamberts and the necessary light-measuring methods are explained. Permissible mine illumination systems (fluorescent, mercury vapour, high-pressure sodium vapour) are presented.
