1. A resin input nozzle which is configured to engage or connect to a hollow resin-anchored rock bolt to introduce a resin composed of a plurality of resin components, into and through the bolt, the nozzle comprising:
a body with a leading end, a leading end portion which ends at the leading end, and a trailing end;
a first conduit and a second conduit formed through the body, separate from one another, each of the first and second conduits having an outlet, which opens at or adjacent the leading end; and
at least one inlet which is configured to engage with a supply of a respective resin component,
wherein the outlets are spaced from one another to prevent mixing of the resin components as each emerges from a respective outlet after passage through a respective one of the first and second conduits by the first and second conduits diverging, at least towards the leading end, with each of the outlets opening through a side-wall of the body, thereby laterally spacing the outlet of the first conduit from the outlet of the second conduit.
