Abstract
An apparatus for lining a blast hole comprises a tube of thermoplastic material and a welder for welding the tube, wherein an end of the tube can be welded closed by the welder and the desired length of tube can be dispensed and cut free from the rest of the tube when the closed end is at least part way inside the blast hole. There is also a method of lining a blast hole which comprises welding closed an end of a tube of thermoplastic material; placing the closed end in the blast hole and allowing it to descend into the hole; dispensing a desired length of tube; and cutting free the length of tube from the rest of the tube.
Claims14
An apparatus for lining a blast hole comprising a tube of thermoplastic material and a portable thermoplastic welder;
- wherein the tube is held in a dispenser, wherein the tube is in a substantially continuous cylindrical form prior to being dispensed from the dispenser, wherein the welder is configured to weld the tube transverse to a length of the tube, wherein when the welder is operated an end of the tube is welded closed transversely to the length of the tube by the welder, wherein a desired amount of the length of tube required for the blast hole at the site of the blast hole is able to be dispensed from the dispenser, wherein the dispensed substantially continuous cylindrical tube is able to be cut free from the rest of the tube when the closed end is at least part way inside the blast hole.
A method of lining a blast hole comprising:
- providing a dispenser holding a tube of thermoplastic material which is in a substantially continuous cylindrical form prior to being dispensed from the dispenser;
- welding closed an end of the tube of thermoplastic material on-site, wherein the weld is transverse to a length of the tube;
- placing the closed end in the blast hole and allowing it to descend into the hole;
- dispensing a desired amount of the length of tube required for the blast hole from the dispenser;
- and
- cutting free the desired amount of the length of tube from the rest of the tube.
