matériel sans rail

CONT: A la mine Quirke, la production a surtout été tirée de deux horizons de conglomérats, soit le filon ""C"" qui fournit encore la majeure partie du minerai et le filon ""A"" situé, du point de vue stratigraphique, à quelques 45 mètres au-dessus du filon ""C"" et qui a récemment été mis en valeur au moyen de matériel sans rail hautement mécanisé.

CONT: Both tracked and trackless equipment for underground mining is available in Canada. Since the introduction of underground trackless equipment during the sixties, scoop trams, load-haul and dump vehicles and personnel carriers are now being made in Canada.
OBS: trackless mine: A mine with no rails. In these mines, rubber-tired vehicles operating independently of tracks are used for haulage and transport.
