Abstract: A ladderway system for an underground raise includes an elongate tube adapted to generally conform to the shape of the raise. The tube is of circular cross-section to generally conform to the shape of a round bored raise. The tube is formed with a longitudinal slit along its entire length, whereby the diameter of the tube can be adjusted to generally conform to the shape of the raise. The ladderway system further includes a ladder adapted to be mechanically coupled to an interior of the tube. The tube is manufactured of a sufficiently rigid and strong plastics material, such as polyurethane, so that it acts as a surface membrane or liner within the raise.
