"Better Lighting for Underground Metal-Nonmetal In-Mine Preblast Operations"

Printer Friendly Version 		Safety Something YOU can live with!


It is recommended that supplemental lighting be added to elevated lift equipment to improve the illumination in preblast areas, especially in high back situations. With increased illumination, it is expected that blasters and ground crews will better identify loose and hanging rock on the roof or back. The loose rock could then be scaled down before the blaster and others in the immediate presence of the blaster ascend on the lift platform to load blast holes.
