Underground coal miners' foot and boot problems.

The New South Wales (NSW) Joint Coal Board Health and Safety Trust funded an investigation into foot problems reported by 400 randomly selected underground coal miners from 15 mines in NSW. Miners were interviewed and their responses were entered directly into laptop computers. Digital cameras were also used to take pictures of skin conditions and miners' posture. Observations of the skin results indicate that miners find gumboots to be hot, sweaty and uncomfortable. Skin breakdown and tinea, is frequent and disabling and responsible for absences from the workforce that are costly for both miner and employer. A more comfortable and better designed boot is needed, fabricated in waterproof leather together with socks that 'wick' the moisture away from the foot. Socks worn were of varying components and washed at irregular intervals, indicating a need for regular changes of socks and improved hygiene.
