Abstract
The resin nozzle adapted for storing resin set bolts into ceilings and walls of a mine by injecting a resin sausage into a pre-drilled bolt hole, the said nozzle including: a spring that defines a passage to which resin sausages may be passed there-through; a nozzle tip connectable to the same defined passage, said nozzle adapted to extend into a pre-drilled bolt hole; and a connector member adapted to be fastened onto the tuck bolting equipment to which the resin sausages may be ejected there-from.

A resin nozzle adapted for storing resin set bolts into ceilings and walls of a mine by injecting a resin sausage into a pre-drilled bolt hole, the said nozzle including:
- a spring that defines a passage to which resin sausages may be passed there-through;
- a nozzle tip connectable to the same defined passage, said nozzle adapted to extend into a pre-drilled bolt hole;
- and a connector member adapted to be fastened onto the rock bolting equipment to which the resin sausages may be ejected there-from.
A resin nozzle adapted for installing resin set bolts into ceilings and walls of a mine by injecting a resin sausage into a pre drilled bolt hole, said nozzle including;
- a main body that defines a passage to which resin sausages may be passed there through;
- a compression spring adapted to absorb vertical impact when said nozzle inadvertently collides with rock or related material to be reinforced during alignment of said nozzle with pre drilled bolt hole;
- and a tension spring adapted to allow the main body to be laterally flexible such that damage to said nozzle is substantially avoided in instances where said nozzle is not able to be in direct underlying vertical access alignment with the pre drilled bolt hole.
