Low Glare Luminaire for Thin Seam Mining.
Parker JR; Hahn WF
NTIS: PB/83-257246 :102 pages
Work places of an underground coal mine are required (30 cfr 1719) to be illuminated while self-propelled equipment is used. Permissible machine-mounted systems have been developed and applied satisfactorily to many mining operations. However, some low- and thin-seam equipment has been difficult to illuminate because reliable, direct current (dc) systems and compact, low output, low- glare luminaires were not available. This program resulted inthe design and prototype construction of compact, low-glare luminaires and alternate current (ac) power systems, particularly suited to resolving illumination problems on low- and thin-seam mining equipment. Design objectives were based on enhancing the prospects for thin-seam illumination solutions through definition of a product that could challenge markets enjoyed by higher glare luminaires and through reduction of technical risks associated with any new product development as well as the MSHA certification process.
