Surveys of light intensities have been conducted m 19 gold mines where intensity readings were taken at various underground locations. The average levels of illumination in South African gold mines is comparable with those reported in the literature for mines elsewhere. Standardisation of lighting could eliminate variations both within and between mines. Suggestions are made about a guide to mine illumination practice which would agsist in reducing vartabdity. 3.2.0(10(58985) Weinrieh, H.G.
