Victorian coal mines relied heavily on child labor to perform dangerous jobs. Children as young as 2 worked long hours underground, often 18 hours a day, performing tasks like pushing coal trucks along dark, dirty tunnels or opening and closing ventilation doors in isolation. While underground conditions were difficult, children working above ground sorting coal at least had access to daylight and fresh air. Miners would take simple meals like bread and cheese or tea down into the mines to sustain their long work.
